I feel disgusting!!!

I’ve been having sex with this guy I met on tinder for about 2 years. It never turned into a relationship cause it’s just casual sex and I don’t find him to be a good fit FOR ME to be in a relationship. We started having unprotected sex after having a convo about how we’re only having sex with each other ONLY and promising to get tested every other month. Last night, he told me he has a girlfriend now but he still wants to have sex. Obviously I declined but I did ask how long they’d been together since we been fucking for about 2 years. He says they got together a couple months ago and I just feel so nastyyy😭😭. I blocked him ASAPPPPP.

I wish I could tell his girlfriend but I don’t know anything about her😒 he never posted or talked about her on any social media platform we had each other on.

Lol for the comments) I only mentioned telling his gf cause the first 3 comments said to. I never had any intention on stalking his social media to find his girlfriend since he’s already blocked on everything!! Second, I’m not hurt. I just feel disgusting knowing I’d been having sex with a man that has a girlfriend who he’s prob been having sex with. And third, yes we always shared results with the dates showing for confirmation.
