I think my boyfriend's cheating on me

Hey Peepz,
I need some advice...I have this boyfriend and well we havnt been communicating lately. I'm getting this that he's cheating on me. When I asked him if he wanted to talk about what's going on between him and I he got really pissed off and hung up. Then the last time I called...I heard this girl over at his house and it sounded like she was having a good time. So do you think I'm getting jealous or is my boyfriend really cheating on me? cause I donno and like I have no idea what to do either. Please Help ME!

if a guy dont respect u thats one thing that would piss me off and u shouldnt think hes cheatin but if he dont wanna talk 2 u bout it than he aint worth ur time

if my bf did that then i would dump him so quick but thats just me talking!! if u don't trust him then theres no point going out with him! do what U think is right..
