How to know if a guy has a girlfriend?

[Anonymous]

So there is this guy I like. We match each others energy pretty well not going to lie. We joke to each other and stuff, but I don't know if he has a girlfriend. He’s never brought up a girlfriend. I know one time in class I told him that I called him telling him I wasn’t going to make it to class, I had to leave a voicemail because he didn’t answer. I made the comment and he literally stopped and said you called me. And I said yeah. After that he literally grabbed his phone and I don't know if he tried to find my number to put it in his phone but the whole time he was smiling. A couple days later I was meeting him for a test and I was at the wrong location. So I called him and he answered the phone “Hey and my nickname.” Last time we were together he wanted to know what my favorite college football team was and him going to the rival school I didn’t want to tell him. He didn’t give up so I caved and told him. And someone actually picked up on that like why I didn’t want to tell him. He’s the absolute sweetest thing, but I don't know if he has a girlfriend. With all of this does it seem like he’s interested or is he just trying to be nice and friendly with me? I will ask him for drinks as it feels like I owe him one for helping me out.

Just say you'd love to have a threesome, if he has another girl he'll forget about the consequences to try to make it happen. When you're a guy in your teens to early twenties and the opportunity to pull a threesome comes up, your brain shuts off and you just turn into a potato masher for a while.
Jealousy, being single after, well, those are tomorrow you problems.

There's only one way to find out, when you ask him out, if he says "I've got a girlfriend", otherwise he's likely to accept a date.
