Had to Cut Him Out of My Life

Hi, Reddit. I've posted before about my mess of a relationship with this boy but I don't expect anyone to remember because it's been a while. The condensed version is: we flirted, then messed around, I fell in love, he felt nothing. So I told him we had to stop messing sround but he assured me we would remain friends. For a litle while it was kinda awkward but we did remain friends. Then he started hanging out with one of our really close mutual friends without me. A lot. And stopped inviting me anywhere. They are so close people constantly think they're dating, and that's so hard for me to hear because I wanted nothing more than to date him for months but no one would've ever guessed it. Over the weekend, I asked both of them to hang out, and they pretty much both blew me off. On Saturday night, I was hanging with some other friends, and found out that not only were they hanging together without me, but they had blocked me from viewing their snapchat stories to hide it from me. Now you have to understand he's not a bad guy. He's such a nice guy to everyone else except for me apparently. But I wouldn't let anyone else treat me like he does. So yesterday I told him that at least for a while I can't be friends with them anymore and I cut them out of my life. It's the last thing I would ever want to do, but I just can't take it anymore. I feel good about my decision but I know I'm gonna miss him so much. I just need some comforting right now I guess. I need to get over this guy because he's an ass to me.
