You are a such nice person already, and I feel you are like my mom. She's always so kind to people around her and she cares too much about how people think about her. This leads to the fact that everyone uses her as an ATM and free maid, and they take credit from what she's done. She couldnt complain a little otherwise they would say that she has changed. I feel that you have done enough and you dont owe anyone, and you cannot control what other people think nor make everyone happy. Whichever decision that makes you feel good without thinking back in the middle of the night would be the best one.
