Advice about how long to wait before dating again after a breakup varies wildly and mostly isn't useful, because readiness has more to do with what you've processed than how many weeks or months have gone by. Some people are genuinely ready sooner than a rigid rule would suggest; others need much longer than a “get back out there” culture tends to allow for.
A few honest signals are more useful than a calendar. Can you talk about your ex, or the relationship's ending, without it dominating the conversation or triggering strong distress? Are you looking forward to getting to know someone new for who they are, rather than mainly looking for validation that you're still desirable, or a distraction from being alone? Have you had at least some time functioning as a single person — making decisions, building a routine, enjoying things — rather than moving straight from one relationship into searching for the next?
It's also worth noticing whether you're bringing unresolved patterns forward. If you can identify what didn't work in the last relationship and can describe, honestly, what you'd want to do differently, that's a much stronger sign of readiness than simply feeling lonely and wanting company.
None of this needs to be perfect before you start dating again — some of this clarity only comes from actually being out there again. But going in with some self-awareness makes it far more likely the next relationship is a genuine choice, not a reflex.
