Idk what to do…

So me and my bf have been together for 7 years about 3 years ago i found out he was paying for only fans. & I forgave him. fast forward about 2 months ago i found out he was still doing it. I forgave him AGAIN! This would be a deal breaker for me but now we have a 4 month old & are living together. it hurts because he was on onlyfans while i was going through my 6 weeks PP & when i asked him why he was back on one of the reasons he said was because we weren’t having sex. I just feel i’m lost in the situation because i don’t think he’ll ever stop. & everytime i forgive him i get more disgusted with him like i don’t even wanna have sex with him. Then i’ve always told him about liking girls pics. i have all his accounts expect his facebook. i checked that the other day & he liking all these girls pics. & only fans links. He swears up & down he’s still not on only fans anymore but why would u be liking their links ?
