LB, If you speak to divorced guys, you might hear a different story. There are guys who are divorced from abusive wives who are shunned by the community who are often more likely to take the wife’s side.
It probably happens both ways, and I have no idea which is more common. I do have the impression though that often people are more likely to take the wife’s side.
In this case, the OP did not complain about not being invited to simchas, so it doesn’t sound like that’s the issue.
and btw, we don’t know if the OP is male or female. Why are you assuming it’s a she?
