MIL thinks her son should support her financially
I have a slight dilemna that I go back and forth with. My MIL who was a single parent and raised 4 kids who turned out well and love her deeply, lives in our house. I am married to her oldest son. She retired from a successful teaching career and receives a nice pension as well as social security. (She also has 401 money that she doesn't even have to touch). She pays us $600 a month and lives in a fully equipped in-law suite. She does not have to pay any utilities at all. The only other bills she has are ones she creates herself (shopping, car payment, credit cards) other than $600 she pays for medical insurance (she has serious health issues).
She keeps hinting to me that she can't wait until my husband makes more money so that she doesn't have to give us the $600 anymore. I have a problem with this. I don't think anyone lives for free, and I don't think my husband and I should support her finanically because she doesn't need us to. I also don't think that $600 a month is too much money for her to pay us.
Am I being selfish? Does she have a right to assume that since she raised my husband well, that he should support her? In my opinion, she already has it easy. She will never have to worry about a mortgage or rent increase. She doesn't have to pay taxes. She doesn't even have to worry about home maintenance or lawn care or trash removal. Am I selfish for thinking she needs to continue to pay us even when my husband is making more money, or is she being selfish for assuming she's earned a free ride?
Thank you for reading this and please be honest. I haven't discussed this with my husband yet, but I will have to soon as he is now working in a very lucrative position and my MIL's hints are coming more often.
