So firstly, I really do care about my step kids. They are a lovely pair and my gripe isn't with them.
But oh my God, my DH drives me nuts with this (I admit fairly minor) habit!
Basically every time we are eating, he will offer whatever we are having to the children (if we aren't having the same thing).
For example, quite often they stay for a few hours (separate to their nights with us) if their mother has something she needs to do after work and will have already had their tea. They usually end up here when me and DH are just about to have our own tea and every time he will say 'do you want some of this' and cut mine and his portions in half to give to the children who then usually say they don't like it and leave it.
Recently I've been asked by the doctor to cut out certain foods to try and isolate something they believe I'm having a reaction to. The alternative isn't very tasty so I buy this for myself and then DH and the kids have something else. Yet every time when mine is being dished up he'll ask the kids if they want to 'try' some of what I'm having and will sure enough take a slab off my plate for them!
If I ever buy a chocolate bar for myself I hear him telling them if they ask nicely I may share it with them. Which is fine by the way but it's every. time. It's as if I have to hide it from him as well if I ever want more than a square of chocolate to myself.
I snapped the other day and asked him not to offer a portion of my 'special' food because it just goes to waste, they never like it and then I have to buy more for me.
I sound like a greedy cow but it drives me bloody bonkers! I don't mind sharing and will often ask if they want to try some if there is plenty to go around and we haven't already started cooking but I just want to be able to eat something without worrying it's about to be cut in two!
