Boyfriend says hes asexual but is fine with Blowjobs

My (22F) Boyfriend (27M) claims hes asexual. I know this sounds toxic but listen: at the start of our relationship (4 years ago) he was VERY sexual. Since i am too i didnt mind. It was when it slowly started to decline that i did start to mind. The s*x got less and less, only one thing stayed which were the bjs. Whenever i actually wanted s*x and/or get off too he declined or redacted himself. I could get him off and ask him if he could do the same for me he was like "oh uhm idk". What also doesnt help is that he kept flirting online and rping s*x with his friends online behind my back. When i found out and said that i wasnt okay with this he didnt stop and tried to keep pushing boundaries saying that it wasnt real and that he was only attracted to the friends online characters. My sexuality stayed the same and now i feel like my feels arent being met and that it wasnt fair that he was only interested in bjs. I am not sure what to do since he also stopped cuddling and is generally not very affectionate anymore. He also often gets amgry at me out of nowhere. Is our relationship falling apart or should i still try to save it? I cant and dont want to force him to have s*x so i dont push him but i cant force myself to not want to have s*x. An open/nonmonogamous relationship wont work. I do love him and he says he loves me and i dont want our relationship to end but i am unhappy. Is there something i/he can try/do?

Tldr: boyfriend says hes asexual but wants BJs and kept flirting with friends online
