<human>: I am 19 years old and he is 26. 
We met through a friend and things started off good but since he was a shy guy it was just slow paced. I didn't expect a relationship out of meetin him., but after a while he would be around me kissed me, and so on. Then things started moving on from the petty  stuff he would hold my hand in front of his friends, come over to his friends house when I was there, even drive out to my house or m friends house to hang out. I didn't think things were Wierd at all besides him not being much of a talker, just a really shy guy. 

Fast forward to being at the house we always hang out at. My friends boyfriends house. His brother ended up having feeling for me and everytime I would say no thats not how I see you your more of a friend and then one night we got really drunk my guy left and brother tried to make a move on me. I was blacked out. The next morning they told me we hooked up but I thought they were messing around because I know I would never hook up with him and didn't think that brother would do something to me when I was that drunk. 
I wanted to tell my guy but everyone said not to say anything, which again made me think they were messing around. 

Now two weeks ago my guy and I were fine. Saw Eachother sat talked in his car kissed whatever. Then the next Tuesday I saw him I gave him a hug an after that he just ignored me. No reasoning I didn't do anything wrong. Or at least from what I know.. 

Could brother have told him we did stuff, or could they have lied to him about me.. Or it it just normal for guys to stop talking to you

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Been talking with a guy who liked me oh so much, as everyone of his friends said, and now won't even look at me talk to me anything. What's the deal?!
