My wife of 10 years constantly invites her ex lovers, ex boyfriends, ex husband over for family gatherings..?

You sound like a complete gentleman. She needs to be put in her place though. I find that type of behavior unacceptable. Inviting exes over seems a bit odd to me. If my spouse had an issue with it, I would compromise and work things out so that he felt comfortable. You shouldn't have to put up with it and I'm sorry that you do. She needs a lesson on how to treat you, her husband.
