I'm hurt, he was such a JERK!! Help?

We are both 19, so we met last semester abd it off! We hanged our all the time, and texted everyday. We started to be FWB which was a horrible idea which I know. Pls dont criticize I know. So ever since we started that, at first he was so excited to hang out and always blew me off last minute. We started school this week, and it went better. Long story short, we had plans tonight and it was all set. Hw canceled me again last minute via text that he had to paint something at his relatives place. I asked him to call because I hate text messaging. He said he will at 8pm, he texted saying again how sorry he was and how much work he had to do. He told me before that he hates painting so I can't comprehend Wht he would ditch me for painting. I was harsh telling Him that I'm offended thar you blew me off and you can find one min to call. Then he told me that he'll see me when he can and he's not ditching me and well chill soon. I was still mad so I said all is good but I'm nonchalant to continue. So then he said sorry bye. A few hours went by so I thought maybe I was too harsh. I Texted him saying that I understand the family thing and I'm sorry that I was harsh and overescted. Never answered, I just feel saddened and confused? Was I wrong, or was he? Help me - I think I like him and I dont know who was at fault and what to do?
