My children have no respect for me after borrowing my money without paying me back

DEAR ABBY: I have grown children, grandchildren and a great-grandchild. I don’t know if they think I am senile, but they seem to think I must cater to their every whim. Most of them are self-centered, thinking only of themselves. They borrow money from me, and sometimes I let them know it is a loan. Other times I give it to them and tell them that it is a gift. Loans are to be paid back. When it’s given to you, it’s yours.

One daughter, “Marie,” borrowed a large sum of money and agreed to repay it in installments. She paid me back a portion of the money I had loaned her. When the next installment was due, she claimed her first payment was three times more than it had been. When I called her on it, she insisted she had given the higher amount.
