The short answer
NCI sets no waiting period before a bereaved person forms a new relationship. It says normal grief symptoms lessen between 6 months and 2 years. Any deadline you have been given came from a person, not from evidence.
NCI's bereavement guidance gives no rule about when to start a new relationship.
For most bereaved people, grief symptoms lessen between 6 months and 2 years after the loss.
Grief bursts, short periods of very intense distress, can happen.

The whole article, with every detail and caution.
Start with what is not there
People will tell you a number. A year. Two years. Whatever their own family did. It is worth knowing, before you weigh their advice, that NCI's bereavement guidance contains no such rule. We found no mention of remarriage, dating, or a respectable interval. Nothing in the guidance supports the number you were given.
What the guidance does say is that grief symptoms usually lessen over time, in a range of months to years. That is the closest thing to an official answer, and it points away from deadlines entirely.
The only timeline NCI offers
For most bereaved people, symptoms lessen somewhere between six months and two years after the loss. That is a description of how common grief tends to behave, not a license that activates on a particular date.
Two things follow. First, if you are still deep in it at eighteen months, you are inside the range NCI describes. Second, if you find yourself wanting company earlier than you expected, that is not evidence that you loved the person less. Grief does not run on a fuel gauge that has to hit empty before anything else can start.
The question is not how long it has been. It is whether you are choosing this or escaping into it.
Grief will still be there
NCI describes grief bursts, or pangs, as short periods (20 to 30 minutes) of very intense distress.
New relationships are dense with reminders that no one saw coming. A restaurant. A phrase. Realising you have to explain your whole history to someone who was not there for any of it. Grief bursts are a described part of grief, not a verdict on the new relationship or on your readiness.
Isolation cuts the other way
There is an assumption that waiting is always the safer, more respectful choice. NCI's account complicates that. It says a lack of social support raises the chance of complications in grief.
One other finding is worth naming, because it runs against the usual stereotype: NCI reports that men have more severe depression than women after the loss of a spouse, possibly because they have fewer social connections.
None of this means dating is treatment. It means that a life which has narrowed to nothing carries risks of its own, and those risks deserve as much weight as the fear of moving too soon.
Children in the middle
NCI does not address how a new relationship affects grieving children, so nobody should pretend it does. Two things from the guidance are still relevant.
NCI says children often worry, "Who is going to take care of me?" It also says children revisit the loss at developmental milestones as they grow. A child who accepted the death may still find a new person at the table difficult, and may struggle again years later without that meaning the earlier acceptance was fake.
NCI also advises direct language with children, such as saying "died" rather than euphemisms.
How to actually decide
Since no authority is going to hand you a date, the useful test is a private one. Are you looking for a person, or looking for an exit from your own house? Can you talk about the person who died without it ending the evening, and also without pretending they never existed? Do you have support that does not depend on this working out?
And if the deciding itself has become impossible — if guilt is running the whole show, or nothing has softened at all since the funeral — that is worth raising with a bereavement counselor. NCI describes complicated grief as grief that lasts longer and significantly impairs functioning. NCI says cognitive behavioral therapy shows promise for it. Being unable to imagine any future is worth taking to someone. If you ever think about harming yourself, call or text 988 (Suicide and Crisis Lifeline) right away.

Common questions
Is there a decent interval I should wait?
Not one that NCI defines. We found no mention of new relationships in it. Any specific number of months you have heard is a social convention, not a medical finding.
Does wanting company mean I have stopped grieving?
NCI does not address this directly. It says normal grief symptoms lessen over time, and wanting company does not show you loved the person less.
Why does a first date leave me wrecked afterwards?
NCI describes grief bursts as short periods (20 to 30 minutes) of very intense distress. A new relationship can bring up reminders of the old one.
My children are upset about it. What does the guidance say?
NCI does not cover this situation. What it does say is that children often worry about who will take care of them, and that they revisit the loss at developmental milestones.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
