Context I (25 f) met my bf (40 m) in the end of 2018. It was a rocky beginning but I joked about me getting my tongue pierced and needed to find someone to take care of his needs. I was at the time 170 pounds I'm currently 270 pounds. I'm diagnosed schizoaffective bipolar type and few others. I became medicated and gained weight. We've not had sex in 5 years because he has continued to say my weight is the problem. We've hooked up with alot of woman through out the years, in the last year he has admitted to cheating on me and I've found messages of him trying to hook up without my knowledge of it. I'm not getting any sexual needs met by him since 2019. I met someone I want to connect with for I would guess a Fwb situation. I've spoke my needs to my bf last night and I asked his thoughts today and he said no and has been ignoring me. He's incredibly selfish and he admits that. I talked about this to a close friend of ours and he said he would go to bat with me. I just don't know what to do.
