Am I overreacting?

I know there’s gonna be three possible answers to this. One you’re overreacting, two youre underreacting, or three it was to early to tell. But I need advice (more like reassurance) I went on the dating app after a year of celibacy and keeping to myself when it came to romance and men. I matched with this guy and in the beginning it was going really well. We were texting. We made plans to meet up. We were talking basically every day. There’d be a day here and there where we weren’t in communication but obviously that’s normal. We met up and went on our first date and he had to push it back because something about his car but it’s funny because something happened with my car too so I would’ve had to push it back also so we ended up going on a date and it was really really great. He texted me literally that same night when he got home we were talking still pretty normal. I mean there were times where he’d take hours to reply, but I am fine with that style of texting as long as I know you’re still into me so come our second date and we planned on Wednesday ahaed of time and came Wednesday. I was like OK does 4 o’clock work and he was like OK actually 8 o’clock is better. I was like OK that’s better for me too. Sounds good. Come 8 o’clock. I have to text for the update. Long story short he was two hours late. He picked me up at 10 and it kind of felt like it was almost a bootycall but that date ended up being pretty good not as good as the first and the next day I ended up texting him because I feel like I should be reciprocal in this showing my interest so he takes hours to respond and he says the excuse of sorry I was sick so then my mind automatically goes through OK clearly he’s not feeling it as much anymore. Maybe it’s because we had sex I don’t know. So I was upset with the fact he was later than he said he would be and now I’m upset with the fact that his texting has completely slowed down he’ll take a day or so to respond and so it got to the point where the energy and effort feels so off, but he’s still replying to a degree so anyway we were texting yesterday and I said am I ever invited to your house and he didn’t answer me for a day so I was like OK I guess I’m not. I double texted him something like that and he texted me today and said maybe next week? And after that I was like this is too much uncertainty for me too much unpredictability. I’ve already been there done that and dated enough guys to see the pattern arising am I overreacting or did I do the right thing because I texted him back to the next week message and replied I’m actually all set with this. I hope you find what you’re looking for. Was I right or wrong bc it doesn’t feel right because I’m still so into him, but I’m just not into the feeling uncertain when it comes to texting esp only 3 weeks in?
