Wow. I didn't know Tinder was for making friends. So this guy is kissing you and you're kissing him and you're still wondering whether he likes you? Of course, he's been drunk and high both times, but that's usually what people do to let their inhibitions down. So yes, I think he likes you. The question is, do you want to go out with a guy whose only way to express his feelings is to get drunk or get high? Why don't you know how to take his advances? And why did you instantly decide to be friends? Guys don't decide to be friends. That's usually something they say when what they really want is something more. And since you met on Tinder, I assume that's what this guy wanted.
