Also, I would NEVER say or infer that about my wife. She would be crushed if she knew I said or wrote something like that. Sorry you think it is funny to say/ write things like that about your wife. I hope things improve for you.
I have 4 kids. The first 3 we found out my wife was pregnant about a month, less than 2 months, after deciding we were ready to have kids and stopped actively avoiding conception for each of the first 3. The last child it was several months later. My wife avoiding sex/ going to bed early was not the problem. Sorry that is a problem for you. Apparently frustrating.
