Being blamed for something I didn’t do 🥺

**It’s a little long but please read** after reading it I know it’s a little complex

I need some advice: should I reach out to a close friend of someone I used to be fwb with and tell her it’s not my fault?!

Long story short: I had a fwb with someone I really liked. It became a fwb bc with what happened in his last relationship, he wasn’t ready to step into a new one. He was making sure he didn’t end up with someone like his previous partner. At the beginning I know that deep down he liked me. As time went on there were problems that weren’t bc of me. A couple I do admit it was my fault but most were not. Not related to both of us, but there was a third party that I knew (she was platonic, aka my ex Bestfriend now) she got into my Apple account and started bothering both of us. It’s hard to explain but she saw our messages, got into my social media account, saw his stories and started bothering us through ***. It got soo bad that I had to get law enforcement in and that’s how I found out it was her and I made her tell me once I found out who. Idk what happened but one week we saw each other and the week where I confronted her, he stopped *** with me 100%. Blocked me, doesn’t want to speak to me anymore, and etc. I’m trying to tell him that whatever happened wasn’t bc of me at all but he’s ignoring it. 

At that same time, I realize that this person who is closed to him blocked me as well. Now throughout our time I didn’t tell anyone we were talking or fwb. I believe he told this person to get advice to make sure he wasn’t picking a wrong person. Since he wouldn’t speak to me and they both think I am something I’m not, I was wondering if it will be a good idea to reach out to her and tell her my side of everything that happened?
