When you get married you take a vow for better or for worse!!!! That is the bottom line. That was the agreement going into the contract. Just because he isn't getting what he needs at the moment from your mother or for the last few years, that is no excuse to run off & see another woman. He will have enough chance to do that after your mother is no longer alive. It is his responsibility to take the best care of HIS WIFE NOW & see to it that she has the best care.

If he insists on seeing another woman during this time, I would demand on being named the "power of attorney" for her well being since it is obvious that you will be the only one truly concerned with her complete well being without any other outside influence.

I know that the value of marriage doesn't exist anymore.......even though I am separated from my husband, I have not had another man in my life at all for the last 16 years......so it isn't something that is necessary (from first hand experience). I don't believe in any reason he could give for being unfaithful to his wife & that would be the stand I would take if it were my dad.......what they do after the other spouse dies is completely free & up to them, but until that point, they are responsible for their marriage vows & faithfulness. This is a strong opinion & moral value that I will always hold to.
