I'm not sure if this is normal or not and whether it's actually a problem.
ExH and I separated over a year ago. DC's now aged 3 & 5 still talk about/draw our family as mummy, daddy, DC1 and DC2. I guess that's fairly normal.
They still ask why we can't do stuff together or why for example I didn't go to Ex-BIL's party. I just say that we now do things separately and that way they get to do twice as many fun things.
If I say how much I love them they'll say "and you love daddy as well don't you". I say that we are just friends now but DD1 argues that I love him as I'm his wife. I have said that he or I might get married to someone else or have a bf/gf. DD1 thinks that is very odd.
If they make a wish they say they want daddy to live in our house.
They see him a lot and we have stayed civil/friendly in front of them.
Is it just a matter of time? I believe that they think ExH's gf is just a friend. I wonder if it would help for them to know he has a gf?
