Do I reach out or wait?

I’ve been dating/ seeing this guy for a month now. We ended up having sex for the first time 2 weeks ago. (The 4th date) before that we would just fool around but I made it known I don’t have sex unless I’m exclusive. The first time I said this (on our 2nd date) he said “I want to be exclusive with u” but then we both decided maybe to wait on that commitment and he said he didn’t want to rush me. So by the fourth date when he agreed he would be exclusive I assumed he meant it. Since we first met we have been texting pretty much everyday (some days it can be just one or two texts) but pretty much everyday (occasionally one day we skip) we have some form of communication.

Some things I’ve learned about him:
1- he does go out with his friends on weekends and he goes pretty hard. I’ve been out with him before and it honestly didn’t bother me though other than the fact he doesn’t check his phone. But he can get pretty drunk

2-he was in a serious relationship for 5 years and they broke up a year ago. Then 6 months later he dated another girl for 6 months and they broke up 3 months ago.

So just last weekend I slept in at his house without him there (he had to go meet a client) and he told me to sleep in and stay as long as I wanted. That whole day we were texting as usual and things were normal.

We’ve been sexually active with each other for two weeks now and after the first time we had sex he even started texting me more throughout the day.

What I’m concerned about is this weekend I haven’t heard from him at all. The most recent text was me replying to him 3 days ago but he hasn’t bothered to send me anything for 3 days. I would reach out but I was the most recent one and I feel it is his turn to send something?

What do I do?
