I've been married to my wife, who is 48 years old, for 29 years. I wouldnt say that we had a good marriage. We had an incredible marriage. I know that no marriage is bullet proof, but I thought that ours was about as close as you could get. 10 months ago, out of nowhere, I get the "I love you, but I'm not in love with you anymore" speech, and she informs me that she is considering leaving. I didnt see this coming at all, and was devastated. Since then, she has become a person that I no longer know. Her personality, attitudes, behaviors, and opinions have changed, and not only have they changed, they are complete polar opposites of what they have been our entire marriage. She has suddenly began accusing me of trying to control her, and her demeanor is defiant and almost hostile. My marriage is falling apart, we are inches from divorce, and I cant figure out why. We've had our "things", like every other marriage does, but nothing that explains this, and absolutely nothing that would come even close to justifying getting a divorce over and ending what was otherwise a great marriage of 29 years. I've heard that menopause could explain some of this and recently heard that there is a new study that thinks that long term use of birth control pills could cause things like this. She took birth control pills for 30 years until I had surgery for prostate a little over a year ago. I'm at my wits end. I dont even recognize this woman anymore, and its destroying our marriage.
