What would you do if your mother-in-law sprung this one up?

My father-in-law passed away 17 months ago. He and my mother-in-law were married for 35 years. My monster-in-law has met someone. They met in June and we have seen him about 5 times. Apparently he visits her very often (he lives an hour and a half away from her, she lives 10 minutes from us). My husband jokes that he (her boyfriend) must not work very much because he spends so much time visiting her.



So she came over for dinner a few nights ago, brought him with her which is fine but we didn't know that he was going to be. No big deal! He's a very nice man and my children all like him. But we hardly know him.



Turns out that they are moving in together and next week they are going to have a 'commitment ceremony'.



We hardly know the man, but she doesn't even care. She won't marry him because of money. She doesn't want to lose the money that she will get from her husband passing. Yet she'll give the example to my children that it's acceptable to live with your boyfriend? She was no intention of ever marrying him.



She wants him and his (grown) children to also be a part of your lives.



I'm sorry but I've never dealt with divorce and remarriages. My parents are still happily married. So go ahead and tell me how wrong I'm being!! I just need to know someone elses opinions. My husband is so embarrased by his mothers actions that he doesn't want to talk about it.What would you do if your mother-in-law sprung this one up?
I say you are right on this one......you should not condone her behavior. nothing wrong with your family seeing or visiting with her....she will always be your hubby's Mom. But, unless you would be happy with your own children making chioces like this......you need to stay clear of situations where your children would think that it is ';ok'; to just shack up with someone.What would you do if your mother-in-law sprung this one up?
Is she happy? You should be happy for her. And, remember, she did not get divorced, her husband passed. Totally different situation. Do you think you fil would be happy if she was depressed all the time and not getting on with her life? Think about how she feels, losing her husband after all those years.
