i am confused and need some clarity about this guy that i recently started dating

So me (F22) and this guy (M28) that Ive been talking to had recently had out first argument. We both had fault in the situation but i was more at fault due to me being petty. He ignored me for an entire day and then he reached out to me and asked if i wanted to come over. I of course said yes ( this being the first time going to his house) and later that day i went to his house. When i got there I apologized for my fault in the argument and he accepted it in a nonchalant way like nothing even happened. we were play games and we took a couple shots and later that night we have sex for the first time and everything went well in my opinion . I ended up spending the night at his place and in the morning we both go our separate ways giving one another a goodbye kiss and wishing each other great days…

i texted him in the middle of that day 3 or 4 hours after i left and he hasn’t texted me back yet , but he has read my message and it has been hours. should i be worried of getting ghosted or am i overthinking.

( more context ) its only been a month and a half since ive met him and we have already had a first date/ meet up at the gym and worked out together. i saw a couple red flags while i was there. i saw female perfume in a hallway closet that he left open and i saw a female black dress behind his bed that i thought was mine when but realized it wasn’t.
