Search Results: not too sure she really likes you

So I have this guy friend and he has a girlfriend and always talks about her, or his exes, or even random girls he thinks are hot, I don't really care and usually give him some sort of feedback about the girls.

We're relatively new friends, I've known him for about a year through mutual friends, but we recently started talking more and he reaches out to me almost everyday to talk otp, we usually talk late night. I noticed he only calls me when his girlfriend isn't around and I've also never met her. He got me a necklace from a popular tv show I like for my bday too. Worth mentioning that this guy is close friends with my ex boyfriend.

So I never really talked about guys I like or my exes. So I decided to try. Anytime I do he just gets quiet or says "mhm" but doesn't engage at all. I told him about one ex and how we had this romantic night and my friend just changed the topic. Even told him about a IG influencer I think is hot and he just ignored me. I also told him about a guy I wanted to hookup with but I was unsure, he basically said "why would u do that if ur not sure?" And when he called me the next day he asked if I went through with it (I didn't) and he said "wow I thought for sure you'd do it". Last thing, I was telling him about how my other guy friend said dating apps suck for guys, his immediate response was "who?", I was like "what do u mean who?", He goes "who said that?". So I told him my other friends name. After he got the name he then engaged in the convo about dating apps

I thought maybe he's uncomfortable talking about other men that way but he disclosed to me about another female friend who told him some guy played her. so he's not uncomfortable with it, he just ignores me I guess.

Am I overthinking this?
