So just to fill in the back story, i have a DD with my ex boyfriend. He's never taken care of her, only seen her twice ( once when she was 2months and once when she was 2yrs) never helped out. In fact he moved out of state before she was born. He's threatened several times to take her away. But my husband is the one who has taken care of her and been dad since day one.(we started dating when she was a week old, and now we've been married for 6 yrs). Although my husband is technically the step dad, dd doesn't know this. She's only 6. Now after 6 years my ex says he now has a newborn son and wants to be apart of her life now. He says he has a fiancee and son and he realizes he's messed up and wants to coparent with us. My dd is very emotional for a 6 yr old and my husband refuses to talk about it, because I'm pretty sure his feelings are hurt from me even considering talking to my ex. I have no clue how to handle this or how i would even explain this to my dd.
