<human>: We've been dating for 5-6 years.

We broke up because i lied to her about things and i did a lot of stupid things after she had the baby.

After months of feeling like shit, she couldn't take it anymore and ended the relationship. We agreed that even though we were broken up, we're still going to respect each other / not hurt each other.   We continued on as though we were still in a relationship. 

I started talking to 2 girls on facebook, one i had liked previously before i met my ex for a long time(B) , and one who is a friend(C) (But my ex already had a problem with C When we first started dating, myself and C took photos of ourselves hugging, and then one of her bent over in front of me.  Stupid i know, i have no idea why i did it, but they were posted on facebook and my ex saw.)   Ex didn't like it at all, but i kept going.   

 I made plans with C to go out to dinner with her a week later. Came back later that night and told my ex "Nothing happened, but i wished something did."  Ex started immediately crying.

I still kept talking to the 2 girls.

I snooped through my exes inbox quite a lot, i showed her mine to prove that i wasn't saying anything and i was indeed "respecting the relationship."  Then she came across me telling C how beautiful i think she is, once again ex broke down.

Ex was sitting next to me while i was on fb, i didn't think she'd see, but she saw me talking about masturbation with B.  She got upset.

I really fucked up a lot of times, and i want nothing more then to get back with her, but now she's told me that she can't because all she'll think about is what i've said and done.

I've stopped talking to the 2 girls, all i want is her. 

What should i do?
