But now it is time to snap out of it, and start the real work on yourself.
So from all of the things you have described, perhaps during the Marriage you were a tad bit boring, and not adventuresome.
Find something you would like to do, something different and take a risk.
I mentioned this before in a previous post, and I don't want you to take this out of context, BUT honestly you have made your Daughter into the focus of your life, NOT your Husband.
Your life revolved around her, and that isn't a bad thing, but I do believe your Husband came 2nd, and your Daughter was the priority, the primary relationship.
Your Husband found someone to have an adventure with, someone to give him the atention he was lacking from you.
So now it is time to do a 180.
It is not too late to save this Marriage, but you can NOT keep on doing more of the same.
Time is of the essence.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
