SBJ.....I am so sorry that things are becoming more difficult.
I understand when you said that you love the woman that she was for 25 years, and that you believe that person is still in there. I feel the same way about my H. I can remember asking him "where did the man that I married go?" I know he is still there, and he is starting to see that he has not been who he wants to be. I can only hope that this self reflection continues.
I don't really have anything to say to make you feel better. Just know that we are here for you, and of course each other. Not sure how I would have made it this far if it wasn't for everyone on here.
I am so happy that you have your faith and your children as a source of strength.
