First, let me say, Happy Early Birthday! I just turned 50 last week!
Your question is a good one, because it does cause alot of problems in marriages. Mine too. The lack of libido, the depression(crying), and all the other 'crap' that our bodies are causing can really make for a tough time.
My husband and I have had our share during my ups and downs with peri. He even had an affair and we almost divorced. He told me that he thought I didn't care anymore and had a one night stand. That was 9 months ago. I had gotten past that part of our lives, but now we don't see much of each other. He is gone all week, working in another town 3 hours away and stays with his mother during that time. I just started a new job and have been having a hard time learning everything(memory is not what it used to be!), plus taking care of my sons, 14 and 12by myself for the first time. I have found myself crying at the drop of a hat and I haven't done that for along time. The stress has caused me to have periods again after nothing for 8 months. I know that it is due to peri. (also, his being gone, brings back the affair)
I think that if your marriage is to work, the men in our lives need to understand this is not in our heads(meaning on purpose) That it is biological and that with hormones out of control, we will do and say things we normally wouldn't. Let him read some info on perimenopause. There are some good sites out there with good info for husbands. What you need to do, is to make sure that you are taking care of him still. That is basically all they want. I try to make sure that my husband is happy. That is what marriage is about. I don't feel short-changed, because when he is home, I feel loved and cared about. He goes out of his way to make me happy.
Wishing you the best!
