So in order to give advice, is it not reasonable that people understand this kind of thought process?
No.
What people need to understand is that abused women's thought processes are the result of being abused. That the abuse is like the boiling frog analogy, and you excuse certain things "because that's what men are like", and it's normalised.
That abused women often think they have a happy marriage, because in their eyes, domestic violence involves being beaten up regularly, by a drunken, lazy husband, so because he's not like that, and they do have times when they have a laugh, and are getting along fine, they don't realise that he's being abusive. The punching walls becomes explained away, because he has a bit of a temper, and they've been gaslighted into thinking that they made him angry, so it's their fault.
Even with all the (sadly) many threads on here, by women suffering abuse, so many people, still don't recognise it for what it is.
And it wasn't just one or two posters who asked the question about having the children, it became a torrent of posts, all asking the question, AFTER OP answered it.
There's no excuse for that.
