Feel like my boyfriend is lying, and i can’t keep bringing it up I look stupid

I brought this up and we had a bit of a talk and he said I often bring these types of things up where we may be different. Yet I’ve asked a lot of relationship type questions and were only together a bit less than 6 months but I don’t feel like we act much like a couple. I feel when he speaks about the future im not included only in the more immediate future. I feel like it’s not romantic it’s more physically affectionate

Ages are 28f, 33m. 2 weeks ago we met for dinner and he said he has to go home after, to do something for his business but I couldn’t hear what he fully said. He often leaves plans after a bit and it feels weird. I told him it makes me sad and he said he has things to do places to be. We’ve been seeing each other a bit less than 6 months and I’m really worried. He also got Covid and couldn’t meet. And when I asked if he’s seeing others or what happened after dinner he said he went to his brothers house to figure buisness stuff out but his brother just had a baby and I recall him saying they don’t usually hang at his place anymore

It worries me when I see my bf and he leaves abruptly because I feel he’s seeing others. It was maybe dumb to tell him. He just moved in with his friend who’s a woman and they’re taking the dog to get surgery tmmrw. I feel like sure he brings me around his friends but each time we meet up I complain

I don’t feel he’s into me. we meet up and talk a bit then kiss. We don’t act much of a couple aside from it. Physically I guess we are affectionate. But I’m so on edge because I don’t fully trust him. But I haven’t dated a lot and each time I did, I got cheated on.
