I’m a homewrecker and didn’t even know it 😔

Well, today i feel very down, the thing is that i i´ve always been very close with my best friend who is a female. I’m a guy, Bisexual, almost 30 years old. She is the only one who i´ve talk openly about that, and her boyfriend was my classmate in primary school and high school, I’ve known him since kindergarten. We have been hanging out together since they started as a couple, like 4 years ago, i actually presented them. Since that day there have been a couple

Issues started. Like 10 days ago, i when out with her boyfriend for some beers and we end up having more beers than usual, we came back to her home very early at the morning, nothing happened, we just had our drinks and talks, that was it (in other days, the same exact thing happened with her). i returned to my home, but her boyfriend showed me some text messages and she was telling him that he was out of the closet fucking with me (they had an argument that day)... i didn't do shit because i thought that was stupid, a lie and nothing to do with me, but i had my reserves with them. Today the nail in the coffin, they asked me if could join them to some errands thy had to do, i said yes because i was bored and free today. His errand didn´t worked out as expected so he ended up inviting us to some beers and other beverages. In front of me they were having an argument, i kinda realized what they were talking about when we returned back, he was telling me about the same insecurities she had the other day, she said that we wanted to be together fucking because i invited them to the next round of beverages, their fight was really bad.

That´s why i´ve always felt hesitant to talk about my preferences. i thought i could trust her because she is like my sister. i´m very respectful and never been attracted to anyone of my close circle, especially if we are talking about my best friend baby daddy (we won´t play with that). I felt disrespected, something that never crossed my mind, i never been in this situation before, i don´t know what i can do next, i feel betrayed, because she used her insecurities and my sexuality to fuel that stupid insane thought that she has.
