It’s hard to feel I deserve anything more, I’ve never asked anything much of him. I feel guilty if I say what I want, I’ve given in every step of the way.
I generally say ‘I don’t mind’ to things, even if I do mind.
Unfortunately by having them live under the same roof as you and him in a relationship, you are teaching them that this is what a relationship looks like.
That a woman should do as she is told by a man and keeps quiet to keep the peace, even when uncomfortable.
That a woman should defer to a man's decision making because a man gets to control the mood of the whole family.
That a man is allowed to shout at children and make the family live on eggshells.
That men shout at their partners and even if it upsets their children, it doesn't matter enough for the man to stop or the woman to leave.
Can you live with that?
You say this:
If they were seeing us shouting, or he were abusive it would be different, but for them they are seeing an amicable relationship.
But earlier said this:
DH has a temper and shouts more than me and they don’t like it.
They are seeing all this. And they already think that it's what a relationship is supposed to look like. The longer you stay the more likely they are to replicate your relationship when they are adults.
