How do I get over this guy?

Rodette • 17 👽
I've been talking to this guy for 6 months straight. We went on a few dates before. From going to obsessive daily texting (his initiation, not mine) and flirting to just acting completely distant is a huge blow to me. Should I even be hurt?
From the start, I've been getting mixed signals. However, I just connected with him. We have the best chemistry. So ignored the red flags. 
Now, I just need to get over him. He flaked on me on my formal two weeks prior. He's made fun of my body, saying I had no ass or boobs. He insulted my friends telling me that they're ugly. Finally, he kept talking about how hot my other friend is, even though he knew I liked him. 
So please help me get over him!!
