Do I confront him about possibly lying or just let it go?

We’ve been seeing each other for 5 months and he’s 33 I’m 28. The issue that came up is he leaves early and has an excuse. Once it was the dog got out, another he had a work event, left something important at work, had to go to the gym. The thing is he’ll leave 1-2 hours in and do that. Where he usually texts me when he’s back home he doesnt those times and literally bolts off.

He moved in with a female friend. I met a lot of his friends and he introduces me as his girlfriend but sometimes he’ll walk off and talk to his friends and idk these people yet. It’s hard for me because he seems to think I should just talk to people.

He keeps trying to get me to meet the friend he lives with but seems it doesn’t work out. He told me a lot about her bf/ex. It’s almost like he talks so much about her I worry that he likes her or something is going on.

He also told me once He is friends with his exes and nothing will stop that. Another time I said I’m sad when he leaves like he does. He said he’s very busy. Like he snaps at times. Other times he’s really way nicer and more attentive. We see each other 2-3 times a week but those first 2 months I only saw him once a week. And there was a time I didn’t because he road-tripped with another female friend.

I’m worried that I’m not only not the main gf but I’m a side piece or he just wants to hook up. We didn’t have sex because he invited me to his place a few times at the end of the night and it felt so off. He was hinting at me coming over to watch this show. And then it turned into come over and hang out. I tried to give this more of a chance but I’m scared I told him too much. That I want a relationship that we should meet each others friends etc.

When I bring up my hobbies or interests he doesn’t ask. He never complimented me much. We just talk and then kiss. Literally all there is. There’s not much going on romantically. I feel like I just let him take the lead with the hand holding and stuff, because I’ve tried to just look at him after we kissed and there’s really not much there. He either wants to kiss more or just be physically close. I’m really worried he only wants the physical stuff and he’s playing the long game here. I am also scared he runs off to see other women. Idk if I’m stupid to think this but I’ve never been this way.

I haven’t dated in a while and this is the longest thing I’ve had. Usually guys leave me alone early on if they just wanna hook up and see I’m not
