So after everyone commented on here. I have taken a very hard long look at myself and this relationship with my friend (who I am going to refer to as Lucy). I can see the mistakes that I made and what I did wrong. I can own that.

What I can not do is except the lies she is telling about what I said, I know I didn't. The lie about SS hitting her boyfriend in balls for an hour straight and smashing her nephews face in the chair (that might be true but I think it was then playing around not being mean). If a grown man is letting a kid hit him in the balls for an hour something is wrong with that. I live with this kid and know him, he never does stuff like that. I am not saying he maybe did not get excited playing with the nephew because that sounds like something he would do and SS was going along with it. Why say something now why not say something to me or my SO at the party or tell SS to knock it off. He listens to adults really well. Anyway I know in my gut and my heart that was not true.

In her response to my apology she brought SO's sister into for some reason and she was never mentioned at all throughout this whole thing. She also went on to block me, my SO, and his sister (I really do not know why on this one) all on facebook. I really don't care I am not that big into it. She did not block my mom thought. All so very weird.

I showed my mom the letter to get some feedback as well as Lucy's response. My mom has known her for a very long time, a very long time and they have texted on and off over the years. She said my letter was not horrible but she can see why Lucy would not feel like it was the utmost sincere apology but that her responses were all about her and really just out there. She also thinks that Lucy is jealous I brought my SO's sister with us and I included her, why else even mention her.

My mom I love her I was not thrilled she did this but it is my mother, she showed the letter to a co-worker to get a more impartial person's opinion on everything that was said. If she has asked me I would of told her not to do that. The co-worker did say that my Lucy sounds a little toxic.

SO after everyone's feedback on here and hearing what my mom said and the co-worker who I sort of know but only to say hi quick when I go there. I can own what I did that night and admit my faults. I did apologize to her sister and it was a heartfelt apology. I just apologized for my behavior and mad no excuses for it and did not even mention Lucy in the letter or blame her for anything. As for Lucy I think we are toxic for one another. When I am around her sometimes the worst side of me comes out. While that is on me and I should control it better I think it is time to just cut ties. I should be around people who bring out the good and me and I would hope I do that for them as well, or where we can just be ourselves.

Just wanted to thank you all for the brutal comments they did help me see many errors I made and I will work on. At the same time it also helped to me really look at this relationship in my life. It has caused me many stress over the years and I should not be friends with someone who I feel the moment I say something she does not like it will be war. It happened anyway I know and I caused it but i think the stress of it all and the feelings I was feeling and buried just erupted like a volcano. That is all on me. If someone in my life is making feel that way, truth is it is not worth it. So thank you.
