I have lived next door to my mother for 10 yrs. We could only buy the property because my MIL gave us the money. Now she needs to be looked after we are moving to a bigger property so she can move in. My mother has become very upset and told me she needs us to stay close because she is getting older too. My MIL is 90. My mother is in her 70s. She wrote me a letter telling me how unhappy she is. We live next door and she never does anything with our kids we hardly see her. Need some advice
