I have been married for over 30 years. My husband has few friends and no close friends. He never wants to go out with other couples. He has little to no sense of humor. I found that I am completely bored with my marriage. It has become more like a business than a marriage. I do not desire to have sex with him at all. We have on child left at home, but he will soon be 18. I want to leave, but I'm really afraid of breaking up this family. I just want to enjoy a relationship where there is some fun and socialization with other people. He will not change. I've been in this relationship long enough to know that he is going to stay the way he is. He is a good man to his children and also to me most of the time. I'm just do not feel any passion or enjoyment with him. I'm really bored. Financially, I can make it on my own. What do I do?
