Don't let these drama queens scare you.
You are in love. No doubt. He says he loves you too and you believe him. Great!
You should break it off with him.
I will share my experience and maybe you'll get why I'm saying that.
I was a bit older, 18. I'd been messing around with guys since I was 13, but had never been kissed. It had always been in closets, in cars, in bathrooms...
I was an aspiring actor. I did a play when I went off for my doomed first semester of college. This was the first time I'd ever met openly gay people. The director, Charles, was gay. He was kind. He was 45. He was also creepily into me. I wound up moving in with him because I became homeless. I I thought this was just a kind gesture on his part, but it was because he wanted me sexually and was too afraid to ask. Charles became somewhat obsessed with me.
Charles had a friend, Robert, who was a set designer. He was 21 . Charles invited him to come and stay with us while he worked on our set. He slept in Charles' bed. I slept on the couch. After a few days, Robert managed to seduce me. We were like freaking rabbits. Every moment that Charles wasn't around, we were tearing each other's clothes off.
Robert confessed to me that he had a partner, Kyle. Kyle was extremely possessive and abusive. He wanted to leave him, but he couldn't, he was afraid. I was a brave and had been pretty much raised by bikers, so my reaction was "don't worry baby, I'll protect you!"
Charles walked in on us having sex and threw Robert out. Robert and I had a tearful goodbye and he left to head back home, promising we would have a relationship once he broke it off with the evil Kyle.
A few weeks later Robert came back to town. With him was the evil Kyle.
Kyle was about 35, 5' 3", 120 lbs soaking wet. He was a mathematician. He was shy, timid, and sweet. Not even a little evil.
Robert and I snuck away a few times. Robert insisted that this frail little man was the violently abusive monster he'd described. I believed him.
Robert just vanished one day. Leaving Kyle devastated. They'd been together for 3 years. I was also devastated, because Robert was supposed to be "the one". I hated Kyle.
Over the next few months, I got to know Kyle. Still not evil. Turns out Robert had been the abusive one. Kyle and I became friends. I confessed that I'd been screwing his partner and what Robert had been saying about him. He understood and forgave me.
Robert popped back up a few months later and was furious at me for confessing to Kyle. He took Kyle away and I never saw either of them again.
Looking back, though I thought I was in love with Robert, I wasn't. I had no idea what love was.
Robert was a guy who I found attractive and who paid attention to me. He wanted to get his dick wet. I wanted a castle.
Anyway. My advice to you is to put a pause on this guy. Find some other boys and figure this love thing out. If you're both still interested in a few years, go for it.
Right now, you're just hurting yourself. He's talking about leaving his wife for you. Easy words to say when you have a wife and a boy who will blow you on request at a barbecue. Much harder to follow through with when that 18th rolls around.
