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

Boyfriend goes to military school, majority of males. He got a new phone and downloaded snapchat, his reasoning was to send chats with me. My phone broke had problems got a new one last night downloaded snapchat, tap his name to see who his bestfriends are and they are all girls, none of which are me. 

Problem: I found out that my ex had been seeing other girls through snapchat and facebook. I'm insecure that my new bf is doing the same. I feel like I can't trust him, but I care about him a lot but I might have to call it quits because it's such a stupid little thing but it led to something devastating. I really don't know what to do. I've been distant with him since last night.
<bot>: Boyfriend just got a new phone, he downloaded snapchat with the purpose of snapchatting me. All random girls on his bestfriends list, but not me.
