I am so sorry that his family was not raised to be thoughtful or considerate. He sounds WAY to passive.
Knowing that about me gives perspective on any advice I toss out there.
I know it is not in your nature to tell people off. It appears it is not in your hubby's nature either.
There are hurts and insults that they dish out that you should not be expected to tolerate.
Meeting them on their ground with this thought......
Next time some picture of his ex pops up......
Just what I would say......
"You all must have really thought the world of her. I notice that her picture is pulled out often. It's such a shame you cannot feel that way about me. It makes it hard for me to feel wanted at these family gatherings when even though they have been divorced for such a long time she is still included even though she is not here. "
Then turn and walk away.
They can think it over, say negative crap, or be confrontational....... Brace for whatever may roll from it.
Nothing in what I typed should cause your hubs to have a tude.
