<human>: Can you give me a shortened version of the text?

So I posted in here almost two weeks ago about my boyfriend leaving me because he didn't have time and were gonna have different lifestyles. 

Last night, I was helping one of his friends with their breakup and they reveal that he broke up with me to sleep around with girls in college. Furthermore, he was looking to go camping with a bunch of girls after saying he wasn't gonna sleep with anyone or really want to be around many girls.

He's gone at my city's emergency service academy until Wednesday but I still think I should talk to him about this. I have a plan for how I'm going to confront him but i'm not entirely sure where to start.

I feel insanely betrayed and hurt. I feel like I'm less than his last girlfriend, who he dumped because she started smoking pot and getting drunk a lot. Yet here I am getting dumped so he can go have sex.
<bot>: My boyfriend broke up with me to sleep around and broke his promise of not wanting to hook up with people, need advice please.
