Okay so its been 6 months, me and my ex had a reallly bad broke up over this guy I really like now.. and I thought I was over him until he start talking to me again.. I mean I cried and cried forever for this guy but finally just thought I moved on but he start talking to me again. He brought up all our memories and everything.. I thought I was over it but I start feeling for him again, but I'm totally head over heels in like with this new guy, and I just need help on what to do.. heeeeelp meee!!

There's no way you can be friends with your ex unless you've truly moved on and accepted the fact that what you had was in the past, and is over. Which you have not if hearing of memories and talking to him makes you love him again. So therefore all you can do is go completely no contact and don't speak to him, think about him, or message him. If you love your new boyfriend like you say you do, this may be the best thing to do.

Just remember, it didn't work out the first time, why would it a second?

Stick with your new man and move on from him, and go no contact. For your new relationships sake.
