Is AUTHOR wrong in the post ? POST : I've been having an internal strife deciding whether or not I am being a cold-hearted asshole. So my sister is by no means an angel, but she is family. Her life has been becoming harder and harder these past few months (roughly starting 24 months ago). She broke up with her boyfriend of 8 years, because of her hooking up with a student (high school teacher at the time). She is now dating this student that is 6 years her junior.

Since this change has happened, she started blaming her ex for her compulsively buying clothes, and wasting money on fast food and subsequently gaining a lot of weight. This has racked up quite a few bills, as most of these purchases were on credit despite teachers in our country making a really good living. She quit her job at teaching by not showing up. She was fired and blamed it on her ex because he 'forced her into becoming a teacher'.

She bought a brand new car when she started teaching, these payments were easy to make when she was teaching. Now she expects my father to pay for it, as well as help her with gas money and paying off her debt. My dad is a big softie and is paying for this, slowly but surely. This has my mother pretty upset, however my father told me that he cannot say no to his kids.

She has recently gotten pregnant with her new boyfriend, the student, and is deciding on keeping the child. Her boyfriend is jobless, and has no drive to get a job. She is basically a single mother in this, and expects my mother to babysit and raise her kid when she goes off to work. This has my mom upset, but she agreed that there is no real option outside of it. The bills for the checkups are all coming from my father's pocket.

Now, why I don't feel bad is because she has sexually assaulted me when I was a kid (This has made it near impossible to interact with any girl lmao), her ex boyfriend really loved her and worked really damn hard to procure them a great future, and she has been lying and leeching from my parents because of her bad decisions. Reddit, am I the asshole here?
