@PUNKEY,
Exactly my point, there are many home expens s and they all fall on me, not to mention groceries.
I think he should contribute what he has been paying for rent. He will get a lot more for his money. He lives now in a small apartment with no yard versus a large fully furnished home on 3 acres, heat and electric, groceries, laundry and cooking. I live on the edge of a state park with many sports available. This is a place he could invite family and friends.
I do not want to charge him rent but I do not and cannot carry him either.
His just being here on weekends significantly increases my bills for elec and groceries, he is twice my size.
