My sister, 27, who is 2 years older than me, found her boyfriend on a dating app. My sister was in depression during those days and it was her boyfriend who provided her with emotional support. Now they both want to marry each other.
Few reasons why he is a bad match:
Destroyed her Dream MBA B-school application
Apparently, this guy sucks in English essay writing skills. This guy contributed a lot to her MBA B school essay applications. Our entire family told her to rewrite her essay, but my sister didn't listen. She couldn't get into her dream college and had to settle for some other college. My sister is blind and thanks to this guy for at least helping her secure admission to some other college.
Extremely rude and possessive.
Inappropriate behaviour
When I met this guy along with my sister, he passed a needless sexual joke which made me and my sister both awkward.
Lied about his salary. His actual salary is 40% less.
Unhappy with my sister's academic career progression for own selfish goals.
My sister is blind and wants to marry him only because when she was under depression for 2 months this guy helped her a lot.
The moment I try to convince her about all this, she deviates from this topic and stops listening.
How do I convince her that this boy is not the best match?
