Is it normal to break up with someone and regret it?
Yep.Totally normal
Yes, it’s normal to regret a breakup, even if ending the relationship was the right choice. Missing someone and second-guessing yourself don’t automatically mean you should get back together.
Breakups can bring grief, loneliness, and a lot of “what if?” thoughts. You may miss the person, the routine, or the good parts of the relationship while still knowing the reasons you ended it. Those feelings can show up right away or much later, and they don’t prove you made the wrong decision.
Give yourself a little time before making a big move. It can help to write down why you broke up and what you’re missing now; if you do consider reconnecting, think about whether anything important has actually changed, not just whether you feel lonely today.
