so I've been really good friends with a guy I've known for one and a half year now. This year he's been quite touchy like he likes to touch me a lot I noticed. But I never thought deep about it. We text almost every day, all day about random stuff, these past months I noticed that he has been lowkey flirting with me and he sometimes more touchy but I just saw him as a friend so I didn't question it. also, he has a girlfriend so I thought no way he's into me. Once he was teasing me (he always does that btw) and he said something like "don't worry you're beautiful, if I didn't have a girlfriend I would totally be into you. and from that moment I was like what, I kinda felt joy all of a sudden and small butterflies in my stomach. He once wanted to make a pact that when we're older and both haven't had a boy and girlfriend we would get married. He sends me a lot of mixed signals and I try really hard to ignore them. But when we're together he really makes me happy. We understand each other and he supports me so much in everything and helps me if I need anything. End of this semester we sat in class and just talked for hours. He sometimes tells me about him and his girlfriend's problem and I try to help him every time. One day he had problems with his girl and he wanted to end it. He said he couldn't be with her anymore and that he rather be with me. I talked him out of it even though I really want to be with him but I don't want to be the reason why he breaks up with her. I never told him how I truly feel and he doesn't know I like him, he just thinks I think of him like a brother or something. we never talked about our feelings and he hadn't tried anything, he sometimes tells me that my future boyfriend would be so lucky to be with someone like me. He tells me every time how a good person I am, and that I am one of a kind. Now I don't know how I feel and what to do, any suggesting? I would never break them up or be in the middle of it, I'm keeping my distance, the weird part is that I'm actually fine with him having a girlfriend and I love our friendship, I sometimes just wish there would be more.
