im in that situation atm with my daughter and her father gaz.
i warned him that if he even tries to make my daughter izzy call his gf mummy..i will neck the pair of them! his gf is ok, nice gal, its just him thats a tosser! they aint been together long.
as for my husband Don, he is izzys stepdad so she calls him dada. gaz had no choice but to accept this. afterall, Dons my husband, he provides for this family, hes the one who looks after izzy everyday, put her to bed every night. were having a baby together AND my husband pays for izzys education as izzys dad wont! hes more of a dad to izzy than gaz will ever be!!!
gaz & his gf are having a baby but they only see izzy once a month (as that is only convienent to him!) they dont live together and there not married. my daughter has no connection to gazs gf what-so-ever! izzy will soon have a half sister but thats it!
i dont have any contact with izzys dad gaz now, he does my head in with his smarky remarks! so his gf picks izzy up when they actually have her! everything goes through her. so if they split...im wondering what hes gonna do then? prob just forget about the daughter he already has!
