<human>: I'm not sure what to do with my life right now. Here's the situation:

I live with my boyfriend, we've been together for 1.5 years. 

I have always been madly in love with him. It began dwindling when he started playing video games. He's a lifestyle gamer and I think I was lying to myself when we first started dating, thinking it would just phase out. Eventually, I became emotionally distant. I have my own good friends now.

Anyway, I went to a conference in New York and met someone. I ended up hooking up with him and have still been texting him once in a while back home. I thought it was going to be a one night stand that would never be talked about again, but now that we're still talking... it feels a lot more real.

My boyfriend found out about it after looking through my phone. He has basically held a gun to my head, saying if I don't message him and tell him I have a boyfriend then he's going to leave me.

I'm not sure if I should do it and stay with my boyfriend, or not and break up with my boyfriend.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Felt emotionally distant to my boyfriend because of his gamer lifestyle, hooked up with someone else at a conference, boyfriend snooped and found out, is now making me decide! What should I do?
