So I met my friend David's brother Joe like 2 months ago, I barely met him cause he was in jail for like over a year. We started talking and hanging out a lot and he told me he liked me; we kissed and slept together (not sex) we just had a fun night we started to like each other. Even though I liked him I told him I just wanted to be friends cause I didn't really know him yet. (stupid move on my part) He said he respected my decision but he would still try to kiss me and stuff but I would say no. The other day he had a party at his house and I noticed his brother David (the one I was friend's with first) was kinda upset and was by himself in his room so I chilled with him and we just played video games. Out of nowhere he kisses me and I just went with it, he left me a hickey but we didn't have sex. I felt bad and I told him no and we went back to the living room, his brother Joe just gave me a bad look cause I think he thought we had sex and he saw my hickey. So now he doesn't talk to me anymore but I like him a lot. I feel like I messed up and I should've never kissed his brother; He doesn't call me or text me anymore and he would EVERYDAY. I wouldn't even text him cause he would always text me first and now I feel like crap and I wanna tell him I like him but I'm scared he's gonna reject me now. I have no idea how he feels. Any advice?
