<human>: Can you succinctly summarize the text in 1-3 sentences?

I'll cut to the chase. It was a nasty, NASTY breakup. Words were said, things were broken, feelings were hurt. Anyway, I broke up with him because I caught him flirting, sending dirty messages with someone he used to "casually" date. This wasn't the first time though. And he wasn't the only one.

I shrugged off previous incidents because I really thought he would change/leave his cheating ways behind. Our relationship was toxic from the get-go (and yes I am only realizing this now); people were telling me very early on to break it off and move on, but I was stupid. 

I'm not interested in getting him back, but why I am having such a hard time getting over him. It's been SEVENTEEN days for godsake. Last I checked he's casually dating (the same guy) again. He's having a ball while I'm here moping around the house. It's so difficult. I literally could not stop sending him messages. I've literally been on to him for the last two weeks. He isn't replying. I'm tired. I don't know what to do. I think it's time I give up any hope of a post-breakup friendship. I need to go NC--FOR MY SAKE. 

Listen to me...jesus, after everything he did to me, every foul thing he did to me, I still want a friendship. I'm pathetic.
<bot>: Broke up with my boyfriend of seven months. I'm having difficulty coping and moving on. I NEED HELP PLEASE.
