I had been best friends with F(17) since 3rd grade elementary school, we are seniors in high school now. She was a great best friend, but I started noticing how different we were. She was a player, and slept with handfuls of guys, and never took relationships seriously. I on the other hand only had long relationships and got cheated on a lot, so as I got older I started to not respect that about her. She came over to my house and spent a few nights there, we talked as we always would. The first night, She told me she was really into this guy A(17) and they were talking for about a month. she also told me she was playing 2 guys at her work. The next day at my house she asked if another guy could come over so they can have sx in his car. That same night she asked me if I could call A(17) on her phone and try and get him to be in a relationship with her. I started conversating with him, and related to him on so many different levels, he’s obsessive and has struggles in relationships with overthinking. He knew that my best friend F wouldn’t be a good fit because she had a lot of guy friends. He then proceeded to call it off with my best friend F. The last day at my house I was hosting a party, a party that A’s best friend L(18) was at, but A wasn’t there. I walked in on my best friend, and L having sx. I figured “damn doing as she does always just playing guys and moving along” a few weeks goes by and I’m still thinking about how much I connected with A, I didn’t know how to contact him but I knew I had to find out how because he had everything I was looking for. I eventually found his Snapchat. I texted him, just talking as friends at first. Then more, we started talking more than friends but not in an official relationship. I was extremely happy. While this was happening my best friend didn’t know, I felt guilty, she never dated this guy, never made it official, this guy didn’t want to be with her and she had just slept with his best friend a month ago so I don’t know why I felt guilty. And then I found out she had been in a 2 month relationship, a month after I found out which had been 3 months after her and A broke it off, she then told me she loves the guy she’s in a relationship with so much, I then took it upon myself to break it to her that me and A have been talking and that I want to date him. I thought it was a good time because she loves someone so it can’t be a big deal it was in the past and they were never in a relationship. Nope, BLOCKED! my best friend of 9 years blocked me for talking to a guy she was never in a relationship with, she had a boyfriend and says she loves him then why should it matter? AITAH?
