Hey guys, lately i feel like my girlfriend of three years has been cheating on me lately. She isnt my only source of happiness but being cheated on really stings. She seems distant more often, she hangs out with her guys friends from class and I dont know what to do. Im only 20 years old and i dont have too many positive experiences with women but she was actually great up to this point, i dont know how to ask her about it (or even if she'll tell the truth) but im pretty sure she is. Thanks for taking the time to read this guys, your advice would be greatly appreciated.
