Most Helpful Guy
I think you know that he's not worth dating, but I really think you want to know why he was acting like that. Looking at it from his perspective, I can see how he could take what you said as a blow off and wanted to belittle you for making him feel put off. It should be clear that he is not only insecure and hypocritical, but extremely vengeful and cruel to those he thinks have hurt him. My advice is that you dodge guys like this. No person ever has a good reason for saying or messaging the things that he did to you. I think you're lucky, considering he could have dated you, lied to you, then later you find out that he was a terrible person, on now you're emotionally attached to him.

Sounds like he is massively insecure, or he is a major control freak - either way he's not worth wasting your time on! Definitely has issue! You have him a second chance, and he blew it, don't give him a third!
