Boyfriend or not? Helpppp?

Ok so my boyfriend just asked me out this month on the 12th now its the 28th, he was so sweet when we hungout, hugged kissed me told me how cute and pretty i was, but the thing was he was known for being a player because he is one of the most popular guys in school, but he didnt seem like the type when we were hanging out, so i didnt care and said yes when he asked me out, he was single for a few months so he must have really liked me to ask me out? but the thing was i slept over and **** went down.. like we did stuff and i really wish i didnt because now i feel used, and he was drunk and was texting me, his cousin just passed away a few days ago so he has been really down in the dumps, but he was texting me the other day and was like, come see me or you'll never see me again im gonna do something stupid, you might not hear from me for awhile ask my friend why? i was so confused, then the next day i asked if he was okay and all he said was yea im fine then i asked if he wanted to go for a drive and talk and he ignored me when he was online? then his status on facebook said txt with plans, so i texted him and asked if he wanted to come over and he didnt answer, he doesnt know my sisters number so i tested him to see if he ignored me and got her to text him and he answered her and not me? then his status on facebook now says in a relationship? when he didnt dump me or anything, hasnt talked to me in about 2 weeks? what does this mean im so confused :(
