Ik I have bad grammar?

Why my father of my child we just had baby 2 weeks ago , told my family about his girlfriend and how she is ex and how he wanna co parent with me but he is showing feelings being open emotionally he never was at first. , I look crazy cause he never told me he had girlfriend I didn’t care , I told him that was wrong for him hide anything from me I’d just find myself man , but then he says something like we are co parenting he is confusing me why
