Complicated relationship(?) Advice needed!

Alright so last year I was in a very toxic relationship with a guy who cheated non-stop on me, which after that ended, I’ve had trouble investing myself and my feelings into guys... And recently, one of my oldest friends who I’ve known since high school started talking with me. (He has also gotten out of a relationship a couple months back with a girl who cheated on him.)

So we’ve had a good thing going for a while, just talking and hanging out... But recently the conversations have turned flirtatious, which has come as a shock for both of us I guess? Well, when this started happening, he told me that he didn’t want anything to come from this, and he didn’t want someone to cheat on him again explained how he didn’t want to invest his feelings in anyone. (Sound familiar?) So I explained that I’m at the same place with him and how I understand what he’s saying, and I think it helped him a little to know I had the same problem.

Now after a month, our meet ups have started turning to make out sessions as well as talks about our relationship(?) with each other. I’ve come out to him and told him how I was starting to grow feelings for him, and he said he had the same feelings for me, but he needed to think about this and figure this out for himself, and I told him to take his time.

And just a week ago we finally had sex and it was intimately passionate. However now he hasn’t texted me as much, and I’ve been trying not to read into it... But it is concerning when someone doesn’t text or respond after that... Now I’m back to trying to find reasons not to invest myself with him...

What should I do? Should I confront him about it? I need help!
