Was I the bad guy here?
This past weekend I was talking to two girls, and I pretty much had it in the bag with one of them. Then this guy comes over and interrupts. Apparently he'd been buying her drinks earlier that night. He completely ignored me and started making moves on her.
He was not doing well at all. She was being polite and indulging him, and I could tell he genuinely believed he had a shot. Then he asked for her Snapchat (amateur move, btw). She got super awkward, pulled out her phone, and was clearly stuck between adding him and trying to find a way out of it without being rude.
He said something like, "I'm just trying to be nice." That's when I started messing with him. I started saying stuff like, "Aren't you going to be nice to me too? Why don't you ask for my Snapchat?" He got visibly deflated but still tried to save it, mumbling, "You're not really my..." so I said something like "What, I'm not your type to be nice to?" By this point, both girls were laughing hard at him.
I could see him break. He looked genuinely sad, almost like he was about to cry (the guy seemed around 35–40). He just said, "OK, I see how it is," and walked away with his head down.
It's been days, and I still feel a little bad about it.
On one hand, he was technically there "first", he'd been buying her drinks all night, and even though she wasn't interested, she kept letting him do it without ever saying anything. I'm not a fan of women stringing a guy along for free drinks.
On the other hand, I can't stand guys who barge in like that mid convo.
So I would like to hear your opinion. Was I the bad guy here? Should I have just let him do his thing without interrupting? What would you say is the best way to handle these situations?
