I have a question for you and I want you to think long and hard before you answer it. What happened approximately 18-24 months ago? A promotion, death of a family member/friend/co-worker, lost a job, health issue? Something trigger his entrance into MLC.
MLC is about growing up and facing the demons of his/her past. At some point, when he was child, he was stunted emotionally. That could have been abuse of any kind, authority figures not validating his feelings or recognizing him him for his accomplishments. It could have been that he was compared w/someone else and always told that he wasn't good enough. So, when a crisis hits, they have to go back to that time and revisit it, learn to accept the things that they can't change, i.e., face their demons, and then begin to grow up. Some make it out the other side and are the same, others return, but continue to maintain some of the MLC traits and others....well, they stay in the crisis mode and become angry and bitter "old" teenagers, never happy w/what life has given them.
I suggest that you get yourself check out by a physician. They may say they are using protection or not sleeping around, but they have the mindset of a teenager who thinks nothing will ever happen to them. You do not want to receive the gift that keeps on giving.
So, do you think you are having a sexathon? The reason that I am asking is because depression manifests itself in many ways...some want a lot of sex and others not. Some eat and sleep more and others not.
Breathe! Keep the focus on you and know that this is not about you even though you've been forced on a journey of the confused and unknown mirror image of a husband who is a now a stranger to you.
Also, when you have time, after reading all of the homework, you may want to visit around the forum. You will see that the posters are in different stages of dealing w/their crisis spouse, companion and/or friend. Each crisis person is unique because of their personalities and childhoods.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
