my boyfriend treats me like crap.?

[Holly]

my boyfriend is 5 years younger than me but he acts mature in public. okay so we both had feelings for each other but one day my friend asked me what id get for my bf if I had one for Valentine's day. I replied some video games and cologne or clothes then he was like wow you're the best. five mins later he asked to go out with me and since I liked him I said yes. we've been dating for almost two months now and at school he rarely talks to me. when he does he treats me like another friend. he doesnt even sit next to me for one class or lunch. he makes fun of my hair and clothes and sometimes says rude things to me and my life has been really hard at the moment and he knows that and little rude things like that can bother me. he also flirts with my friends sometimes. he has called them angel, sweetie and baby. he ignores my text and I give him space meanwhile he posts on social media. im sick of this can someonr please tell me how to talk about this to him??
I MEANT MONTHS*****
thanks for the advice
