Scared to date

So I came out of an extremely traumatizing relationship about 6 months ago after 4 1/2 years together. I had sworn off dating, male friendships and anything to do with men. I've recently met this guy who seems like he has his head on right but he did just end a long-term relationship and they share a 1 month old. He's offering to do for me and asking if I need anything but im hesitant to accept anything from him. Am I wrong for feeling this is too risky and to back away completely?! I told him I want to give him the space to go back to her and figure that out. He said he's not going back because things had been toxic and she'd had her addiction issues e.t.c so he's choosing to co-parent and choose better for himself and love himself more than staying in a relationship like that. I also asked why he didn't figure that out before impregnating her. He said he thought things would improve and also asked why I didn't figure out my boys dad wasn't right after our first child together. I told him the same, it was stupidity honestly and also thinking it would get better. He seems like a great guy but I just want to allow him the adequate time to see if he really doesn't want to work things out with her and fix his family. I'd be devastated to start building something with him and then one day he tells me, he's going to go try to make things work with his babymama. Is it my trauma and own experience that's making me project onto him or should I run and never speak to him again?
