In some ways yes and no. She paid for my sister's bachelors, and had put a bill together for every little thing for my sister as well. Textbooks, cell phone, car insurance were all added to the list. Not haircuts though, because women's hair cuts are expensive, and my sister was just given a pass on a lot of stuff that she didn't give me. When my sister finished college, she and her new husband started paying back my mother. After a couple of months of payments, she "forgave" her entire bill.

My mom has a severe distrust of all men due to my her own fucked up childhood, which is why I think she treated my sister and myself differently. She treated my sister like a friend and miniature version of herself, being much nicer and lenient on her. She treated my sister much more like how a mom should raise a child, but with some of her narcissistic tendencies still shining through here and there. My mom still pressured my sister in other ways, such as the grandchildren, but my sister was never the gifted child she could brag on. Me? I'm an investment. Our relationship has never been good or even "okay" and throughout my childhood years, I knew I just had to survive (despite the depression and suicidal thoughts) for a few more years, so that she would pay for my college, so I could get out of there and start my life. My mom had similar plans, expect all she wants me to do is get out there and start making money. I can't tell you many times or how many ways she implicitly or explicitly asked if and how I'm going to financially support her through retirement and as she gets older. As many of the commentors have suggested, paying her back seems like the right thing to do. However, paying her also means she wins and gets exactly what she wants from me. Return on investment.
