Hi, don't know if this has been a topic previously. Sorry if it has.
My son is 5, his dad and I split amicably when he was a year old. Shortly after, the ex met his now wife. No issues with this, she's nice, has a 9yr old daughter herself who my son refers to as his sister. Again, no issues, after all, this situation is all he's ever known.
However, the other night, we were just chatting and I can't remember how it came up but he said he had 2 mummies, I said, no you only have 1 mummy and 1 step mummy and I asked if he ever called her mummy, as normally we and he have always said her name. He said he has sometimes called her mummy.
I was surprised and now cant help feeling really upset and put out about this and a bit pissed that they would allow him to do that. It's not as if I'm not around or not in his life. I also can't help thinking that they do this when it suits them, as in playing happy families when out for the day or for meals, like calling her mummy looks better for them.
I know her daughter calls my ex 'dad'. That's fine if her own dad doesn't mind (he's also very much in her life) but I feel really upset that they dismiss my role like that by not discouraging him. I know she treats him like she does her own daughter, her family the same, and I'm very grateful for this, I know it could be much worse.
I'm not sure if I'm being a bit OTT about this.
Should I mention it to the ex? I've told my son I don't want him calling her mummy but doubt he realises how it's hurt me.
A couple of people I've spoke to said they would be furious but they only have my view.
