Here's what happened. I'm a straight heteroflexible dude btw.

1. A gay friend, who I'm very good friends with, offered me a blowjob and since I was single and horny at the time I said ok

2. I let him blow me quite a few times over the coming weeks/months

3. I got a girlfriend at some point, then we stopped this arrangement and he was cool with it.

4. My girlfriend dumped me and we started the BJ stuff again

5. A few weeks ago I felt bad for him always doing it to me so I sucked him but I immediately felt awful and sick with myself and I told him nicely (not in a mean way) that this wasn't what I am and we should stop

6. Since then he's been cold and distant to me. I texted him a huge message over Chrismas and he just replied "thanks you too" essentially. Every time I try to organize something to do with him, like we used to do before this stuff began, he just says he's busy.

7. I asked people in a different sub and they said it's my fault for leading him on... but I didn't, it was clear from the start that I'm straight and wouldn't love him or kiss him or anything like that. They said I should leave him alone but how can I do that when he's like my best friend and we did so much stuff together? 

Am I really the bad guy here? PS we're both 18 male
