Will my ex come back if I broke up with him?

Will my ex come back if I broke up with him?

If it doesn't, get back together. If it does, send him away. If he broke up with you, then he's the one deciding if the reason still stands. Chances are, he's trying to come back because he regrets breaking up with you and you can take him back.

Should I contact my ex who I dumped?

If your Ex dumped you for another girl, and you run into him, the way you act depends on whether you are still doing No Contact, or not. Definitely do No Contact, in case he had the Ick and you need to purge it! If you are in No Contact, speak to him briefly and nicely, smile, then move along.
