No contact..kids say his dementia worse. He will not let kids help him with finances or daily living. One of the kids found out he's way behind in his rent and I'm fairly sure based on past experience that he's in debt way beyond that. I'm worried if he goes under and is not mentally competent to resolve it that his creditors will expect me to pay. I'm 72 with one heart attack still trying to work and take care of myself and am so afraid of what might happen.
