This is the first time I've ever posted on a Forum! However, once I saw the topic, I had to respond. I've been unhappily married to a Gemini man for 17 years, and am making plans to divorce him. I've made jokes with people along the lines of, "Yeah, I married a man with 2 personalities, and I don't like either one of them!" Everything you've all posted has been right on the money -- the sex has been non-existent, there is no physical affection and his humor is biting and sarcastic. He's not even kind.
We were good friends and we tried to turn it into a romantic relationship ... it just didn't work, and it's taken this long to get to a point where our child is grown up enough to handle a divorce, and our finances will be able to cover 2 households. The irony is that everyone on the outside adores him, but they don't have to live with him. I also think that once the drama of the divorce is over, we'll actually get along much better, and be able to co-parent our child on good terms.
