You took the words right out of my mouth. I cannot count the amount of times I have said, "I do not recognize this man." The things my H has said and done since he left in August, well, that is not the guy I know.
It is that very thing that gives me the strength to hang on. It is obvious that something is wrong with our S's. I am not saying our R's did not need work and we LBS's do not need improving. And we are all doing that work.
Rather, I look at my H as if he is not well. Whether he ends up diagnosed with depression, or it's an MLC or it's a thyroid problem, H is not well and I am not going to quit on him when he is not well. The guy I know would not quit on me if he thought I were sick.
I know it hurts. I am so sorry for the hurt that you feel. But you obviously are a strong person and with help you, we can do this.
