i think it would be a good idea if you worked on yourself. some women thinks that a older man wont change because theyre set in there ways. but i believe that anyone can change if they want to.
i was with my mom when she left my dad of 22 years, and her second husband of 7 years. she cried to me on the phone many years wanting to make both of her marriages work.
your wife may love you, but she mightve fell out of love with you from many years of hurt and pain.
yes, i think that you may have a change. if you do change the things that she complained about. if you give her space so she can clear her head. if your able to start over, to the dating stages. you know this women more than any man.
what i mean is if she separates from you, and she is willing to keep communication with you. dont allow the separations to be bitter, it doesnt have to be.
