There’s a guy I like. We text all the time. He has a girlfriend. He talks about her sometimes but with texting me all the time I wonder when he talks to her.But he’s also really affectionate with me, always hugging me and looking out for me. When we go out with friends his main attention is always on me and he’s usually quite shy.He’s also asked me private questions like have I got a boyfriend and what I’m looking for. We’re both 20.Why is this guy acting like this when he already has a girlfriend?
