He likes you a lot! Possibly even more than the girl he’s with. This could be because things are not going well with his girlfriend, in which case he may split up with her and come to you. Or, they may patch it up and he’ll stick with her. Only time will tell. While he is showing tons of interest in you, beware: He could just be using you to make her jealous. On the other hand, he could be getting tired of his GF, and he really likes you better and wants to date you instead. Whatever the reasons, he’s definitely into you!
He’s definitely got a soft spot for you. But does he like you more than his girlfriend? It’s hard to say. He might not be sure of the answer himself. It seems like his heart is torn between you and her. He still needs to decide who he wants. There’s a danger of someone getting very hurt here, so be careful. If you decide to tell him how you feel, be ready for a positive or negative response. Whatever you do, don’t take things any further with him until he’s made up his mind to end things with his girlfriend.
Sorry, but it seems your crush is all wrapped in his girlfriend. His feelings for her are pretty strong and it looks like they might be together for a while to come. He does like you and enjoys being friends with you, but it’s not deeper than that. If he wasn’t with her things might be different. But he is, so you need to accept that and move on. The best thing you can do for yourself now, is to look for someone who’s free to be with you.
