Right from the beginning of our marriage, my wife caused a series of conflicts with my parents and siblings which created a much tension at family gatherings; I was constantly stuck in the middle. As a result, we saw less and less of them.
It didn't help that she came across to them as being greedy, "That's a nice lamp .... can I have it?" So when I told my parents last October that my wife, their daughter-in-law-from-hell, was demanding half of my future inheritance when they died (+10 years from now?), that was the last straw. They were forced to take legal steps to protect their assets, basically by disinheriting me.
As my mother and I walked into the auditorium lobby, sure enough, my wife was sitting right in front of us with my mother-in-law. She turned to face the other way to avoid contact with us. My mother and I walked on by. My father, following behind us (who is a very classy guy), greeted them warmly, gave my M-I-L a hug and shook my wife's hand before she could take evasive action.
After the ceremony, families gathered in the lobby for pictures with their graduating sons and daughters. My daughter was hoping for one pic with both her parents but it wasn't to be. When my wife spotted us, she ran away and remained in hiding until we left the building. She's always been a coward!
ps: One unexpected bonus of my marriage breakdown has been a rebuilding of the relationship between my parents and me. Now, we talk on the phone daily and see each other many times a week. They feel free to pop over any time they want.... although I hope that this doesn't happen if / when I am "entertaining" a man friend.
