How do u get over breakups?

By not allowing myself to waste time brooding, daydreaming, mourning, or otherwise nurturing those broken heart type feelings. If I find my brain trying to think that negative way, I force my brain to think positive thoughts about the present and future instead of dwelling on what is (or at least should be) firmly in the past. 

I deal with it.

Remind yourself that you broke up for a reason and if one of y'all wasn't happy then y'all both couldn't be happy so there was no point in continuing the relationship. You can't control others feelings people grow apart for plenty of reasons. Don't dwell on the reasons you have to just let it go. you are better off just finding someone who is happy with you and you will be happy with them. It will happen it just takes time and you got plenty of time weather you realize it now or not. Don't rush into another relationship take this time to grow as a person
