What will happen to this relationship?

I know none of you have crystal balls, or any of the sort. But, I’ve been dating this guy for 3 weeks, and he let me stay in his apartment. But later on that day I wanted to go back, and be there when he got home.

I took a pair of keys without me knowing what they were for. I apologized for taking them. Then a couple of days later he said he was “confused” When I asked what he meant he mentioned something about not knowing what he wants to do in life, and whether if he wants kids or not. He also said that (of course) he was scared, and upset about me taking the keys cause we don’t know each other so well. I apologized again, and offered to meet with him to return the keys- but then he said that he was busy with family.

He previously said that he didn’t want to have sex anymore so we could build a deeper connection. And I told him that I agreed.

Yesterday I sent him a text asking if we were going to be over once I gave him his stuff back, and he said “I don’t know, I don’t want them to be but I’m just not sure”

I don’t want things to be over either, but at the same time I just feel like running away, and not knowing what his decision is. And on the other hand I feel like I’m being strung along.
