Advice needed, need your take on the situation

So ladies, I need some advice, if you were in the situation I want to know how you handled it.

So there’s a guy I’m in the processing of getting to know. We are doing this with the intention of beginning a committed relationship.

The only set back for me rn is that him and his baby momma sleeps in the same bed with their kid. Now I have no doubts but this definitely changes things for me as I don’t like it. I’m all for them doing what’s best for their kid but it has me wondering if there’s even a place for me. Am I interrupting something here. I don’t want to seem like the type that’s denying a child to have this from both parents but how do I explain to him that I’m not onboard with this and possibly find another way if he’s truly interested in me.

What does on really do in this situation????
