I met this guy a few months ago, we go to the same school but just recently started talking, when we first started talking it was flirty and cute and then it got extremely sexual, it had seemed like he had a girlfriend and I decided to as him about as I didn’t want to be that girl, he said they had broken up but were still close friends bc he’s going out of state for college and she’s a junior. A week later he had posted prom pics w her so I knew he was lying and I asked him again he disregarded it and one night we ran into eachother at a party, we were both super drunk and had sex that night and he had ended up spending the night at my house, we’ve been hooking up ever sense (for about 3 months) and it’s at least once a week we fuck in his car or my car but I’m still worried that he has a girlfriend, he keeps reassuring me he doesn’t but it doesn’t completely seem that way, what should I do?
