So I'm a relatively socially withdrawn college student, I spend a lot of my time alone because I find it painfully difficult to meet people and start meaningful relationships. Recently I mustered the courage to ask a girl in one of my classes out, and a few weeks later were getting along just fine hanging out a few times a week we've kissed and slept in the same bed a few times. 

My issue is that she has this guy friend, for the life of me I have no idea if I'm just being a jealous lonely idiot but I cant help but shake the feeling that she likes him. Last week I was hanging out with them when she sat on his lap and acted all flirty around him, later apologizing when she saw that I could not hide my disgust but today after i went to a campus event with her and told her i wont be able to see her for a few days she let slip that shes going to hang out with him tonight while I go back to my room alone. I feel soo very shitty and I dont know if i should text her or talk to her to let her know how i feel or ask her if she does like him and im wasting my time, or not say anything in fear of ruining a new relationship I really want/need in my life?
