I regret breaking up with my ex. What should I do?

You should try to talk with her about your feelings, maybe yours ex also wants to come back to you.

Talk to your ex. Say what you feel and know How they feel. Say sorry and convence your ex that you realise your mistake.your ex will definitely forgive you. But even if your ex doesn't want to patchup than repect his/her feelings.

Seek out social support. Friends, family, and perhaps a counsellor. Really examine the reasons for breaking up. Have they changed? Feelings of sadness and missing an ex are absolutely normal even if you initiated the break up, but it doesn't mean the reasons for the breakup are wrong. Talking with people may give you insight into whether you're just experiencing normal pain from ending a relationship and losing someone who was a big part of your life. Or if you just needed space and time away from your ex and if you want to revisit the relationship to try to work things out. Ultimately only you can decide what is best to do. You are the expert on you.

Think if going back to them would be the besy thing for you. If so, approach them and apologize.

Go to him. Talk ti him. Tell him yiu think you made a mistake. Tell you him love him still. And if he does not stop you give him a sweet little kiss and ask him if you could be together again? Give it a try.

You should talk to your ex and tell them how you feel. They may feel the same way. If you don’t tell them you feel this way they will never know and nothing could progress

Don't live in the past. Even though it's ok to remember the good times, there was a reason for the breakup. Remind yourself of the reason. It's normal to regret a breakup because we are greiving and we cannot simply shut off our feelings. In time, those feelings will fade, including the regret. Occupying your time and mind are great ways to deal with this. Plus, it's ok to let yourself be emotional and talk it out with someone you are comfortable with.

Try telling him how you feel. explain that you didn't actually want to break up with him & that you were just having a bad time and you accidentally took it out on him.

That is a difficult one to answer and help with. What you really need to look at is yourself and why you made the decision you did at the time and is it truly wanting to be back with your ex or is it because you do not want to feel alone after the break up?

What you can do would be to try to contact him and see if he answers and if he does you can first see if hes single and if he still feels a type of way for you.
