Not really sure

So in sept baby daddy n I had a bad bash and he says he didn’t mean to push his fingers into my jaw bc it was dark and he was walking towards me with his hand already out over an argument and he tried to drive away with my little girls ultrasound pictures so I threw a flashlight to get him to give me back which he didn’t n they later burned in a house fire well anyway. About that time I was around 16 or so weeks pregnant and now im 30 and I picked out her full name n made all these plans and now that he’s come back he wants me to change things around n let him change things around n I don’t think I should whether his kids are involved or not I think the plans I made with my two are the ones I’m sticking with first and foremost.
