dickhead

Hey. So i've been in relationship for a few months, and he seemed so in love with me, I was too of course but I always felt like he's just too different... I'm kind of girl that likes books and art and I value different things, not like all the girls that care only about new lipstick and instagram selfies tha every boy wants... so all this time I had a feeling that my boyfriend would like me to be like the other girls, I mean I dress up nicely and I do my make up pretty great, it's just I don't need to show others that I have money... my bf and I were always fighting over little things and then made up and so on and on... I always thought that he was talking to other girls and he always said that he would never... this weekend I wanted to be with him but he said that he has plans already... and then I saw pictures on snapchat story of him and some girl on dinner and then in club... I got so mad, because he swore to me he would never do that to me just day before! We were fighting earlier this week and we just made up and he did this! Instead of spending time with me! So I messaged him right after I saw snapchat story and told him that I can't do it anymore that I'm done. And he didn't even reply me! He told me he loves me just yesterday and today he won't even answer?! Now I see his story on instagram with his ex with holding hands... what should I do? He never answered to my message about break up... I'm so disappointed in myself that I even liked this dick... some advice ? What should I do?
