No, you are in a good place. This site is exactly where you need to be. Ten months ago I was in a MLC (mid-life crisis) and left my family. I was not myself at that time, no one could have talked sense to me. I was in a fog. Maybe you could say I was ill. Today I am fighting to save my marriage and my family. Take a look at other situations and stories on this site. Read and learn. Most importantly stay strong and don't lose hope.
I too, would really like to hear what it's like to be in MLC. Though he's only 37, it really seems like my H is there too. I guess it hits earlier these days. I will try to look through your posts for your story. I wish there was a way for each of us to put our sitch and a link to our initial (or current) thread on our profile pages.
