Uninvited to his bday party

Guy I’ve (27) been seeing for a little over a month (29) invited me to his birthday party (twice) then when I texted him about it this week, he said he has thought about it and wants it to be just him and his friends. There have been some misunderstandings between us recently and I’ve been pretty frustrated with him and things between us lately so vibes have been kind of weird but I still just think it’s really not nice to uninvite someone, it feels very exclusionary and very high school. I told him this really hurt my feelings and he gave the most bare minimum apology saying he didn’t mean to make me feel bad.

Just a few weeks prior, we were texting more regularly and he’d constantly ask me what I was doing and invite me to things. Now it feels like friends and me are totally separate things and I’m very confused, feels like he has totally pulled it back. Literally a week ago he was telling me I should meet his mom?? When he invited me it almost seemed like he just felt obligated to? He made it seem like I wouldn’t have fun and kept making the point that he’d not be able to hang out with me throughout the party because he’d be talking to everyone, almost like he thought I needed to be babysat? I feel like if I invited someone to something and then later maybe regretted it or changed my mind, I would just have to deal with the situation but it hurts that he went so far as to actually uninvite me because he didn’t want me there that badly? Maybe I’m just taking this really personally but I also just feel like it’s really not nice and I’m very confused compared to his past hyper-interest in me. I even shared my concerns with him about this pattern of men being really into me at first and then once they get to know me, things start to fizzle out. Maybe I just set myself up.

tldr: Guy i’ve been seeing invited me to his bday party then said he changed his mind and wants it to just be him and his friends. Should I be upset that he invited me then uninvited me?
