Catching feeling, hoe, boot camp.

I've had a thing for this guy for forever...we've always been on and off fooling around. Finally I slept with him right before he went off to boot camp (he was huuuuge, the huge where he could just sit back and let me have my fun and it would still be mindblowing). He told me he has stopped talking to this girl who fucks him over every time...like everytime. However I just found out he lied. Point is I'm mad and I don't feel like I have the right because we weren't dating but still like I opened my self up (literally)....and on top of that you lied to me....
