Guy problems !!

Dytaisha
I have been best friends with this guy for four years and we had sex for the first time our senior year . He confuses me because he acts a certain way when he is with me but ignored my text sometimes I asked him why is he ignoring me . He say he isn't ignoring me he has just been busy. Then it's been times where we were supposed to hang out and he never showed up so I don't know what I should do . he text me wanting to hang out I fall for it everytime .  Can someone please give me advice on what you think I should do ?
