My wife would rather be at her friends house

My wife and I have been married for 22 years now and recently one of her friends lost her son to an automobile wreck. Before the accident, she had started going and playing bingo 3 or 4 nights a week. I wasn't real thrilled about it but I didn't say anything. Now they still go and play bingo and are gone for hours but now she is going over to her house on weekends and staying until 2 to 3 am. She never wants to have sex and hasn't for a very long time. If we have sex, it's once a month to once every other month. When she is home, she has her nose in her computer or asleep. We have two kids, our son is 20 and our daughter is 16 and they see how she has become and we are all getting tired of it. What do we do. I don't want a divorce but it may be headed that way.

It takes two people to want to be in a marriage. It may hurt but the two of you need to have a conversation about what is going on. Your wife may not want to be married anymore, or she could be depressed, or she might want more time for her own activities. You won't know unless you talk to her. Your wife might benefit from counseling, the two of you may benefit from counseling, or both of you might need good divorce attorneys.
