your wife was lucky because she had you fighting for her.. see in a way i can relate with you.. i had just got married and my husbands dad had a stroke.. his wife left him because she did not want to care for him me and my new husband moved in with him and i was his sole caregiver... it was the hardest thing ive ever done and i would not of changed the time we had together.. i to made so many mistakes and i always look back and think i could of done this better or that better if i would not of had my mental illness.. i took care of him for 3 years with his stroke and then another year with a stroke and colon cancer he died sharing his life with me and then my husband left me.. he said he knew right after we were married he didnt want to be married to me but i was taking care of his father.. I was so lucky to be able to spend that time with my father in law.. and even thou i was not the best most of the time he was glad i was there.. he told me he was lucky to have me and im sure your wife felt the same way..sometimes doing your best is best that could happen... hugs...pam
