I don't know if I've posted this in the correct place and I'll try and keep it short.
I have two children, 7 and 3. I met and began a relationship with my current partner when I was halfway through my pregnancy with my youngest, as their biological dad walked out. Biological dad does still see the oldest, but doesn't take out the youngest as I've never been keen for him to do this until my youngest wants to go out with them.
My partner gets very upset if I ever refer to the children as "my boys". He thinks I should always refer to them as "our boys" as his wage mostly pays for us to live. I work around 20+ hours a week and I am the default parent. I get up with them everyday (I haven't had a lie in for 7 years) make their meals, do bedtimes, sort all appointments - you get the idea!
If I have something I want to do without the children, he will look after them, but I have to ask days in advance and he's always frazzled and very stressed and quite unpleasant to me afterwards, so I try not to ask.
I can't work out if I'm being unfair to call them my boys as he gets so upset by it. I don't do it often or purposely, it's just a slip of the tongue.
