I have a friend who is married, but probably shouldn’t be. Her husband has betrayed her and it’s pretty bad. However, she still hangs out with him, and that really blows my mind. Whether or not she will get divorced seems questionable. She thinks she is stuck, and I think she doesn’t want to be alone. I am having a party, and I did not invite him, but of course I invited my friend. I have no desire to have the husband at my house, or in my life. To top it off, she has now told everyone what he has done so we all feel weird around him. The question is: Should I talk with her about it before the party? I really don’t want him there. I really don’t like him and my guests don’t either. I know it would cause some awkwardness(okay, not some, but a LOT). But, until they are divorced, they are technically married. What is the etiquette on this situation?
