Should I ?

So I had sex with this guy twice last week I've know him for a little bit...anyways after the first time every thing was fine he was texting back quick he said he wanted to start talking and see if it leads to a relationship..the second time I go over he asked if we can link later bec he had to leave after that day he gradually stopped texting me and replying to my messages and he comes up with stupid excuses as to why, yet he's on Instagram but can't text me back..I don't want to ask why he's doing this obviously because he's not even texting me back. BUT I'm on the verge or egging his house, putting jolly ranchers on his car window, just making him question everything like I'm doing. The more I think about what he did, the more it grows on me. I feel like that would make me feel better...
