Confused, back in the game after years.

So I was talking to a guy online everyday for over month. We met last week and had a blast. Didnt have sex but came close. Tons in common and it was easy. He tells me to let him know I made it home safe and I do and he responds. Still great. Text for the next 3 days, great, and all of a sudden nothing… We had made plans to see each other again and I'm probably overthinking it. But when I asked him if we were still on a few days ago he said he had to see if he could.. We talked and told each other good night ever day for almost 2 months. I text him goodnight a few days ago and got no response. Nothing from him the next day or yet… I havent text him since then. Was trying to give him space and not seem needy or desperate. I dont want to stress this anymore. Do you think he just has stuff going on? He does have children… or did I just get ghosted? Should I text him first? Thanks for any advice 🙂
