I (29M) am planning on getting married to a woman who told me I was her "backup plan" and ruin my entire life.

I (29M) am planning on settling down with a woman who I am not even compatible with. She has told me numerous times that she only wants to marry me for my money, has called me ugly and has told me that I am her "back up plan". She is currently dating other men at this time, and she told me it won't work out with them and she has to settle for me.

I have a good life for myself, got my masters degree in Computer Engineering, I live in my own house, with my cat, and I am making over 100k now. But now at 29, I'm old as a grandpa now and I've never had a relationship and need to settle down, as most people in my city are. (I don't live in a small town, I live a big city)

She won't sign a prenup or anything, and I'll try my best to make the marriage work, but I am not hopeful, she has talked to me about divorce already and I really hope it doesn't come to that but if it does I would have tried my best.

It sucks but now we live in this world, where if you haven't been married at least once in your life, you are considered to be a loser. I am about lose everything in my life and all because I have this urge to be accepted in our society.
