Sadly, if you want children/family, most females will insist on eventually getting married. If you do not want children/family, then you can just get another female. However, it gets tiresome after time and time again as you get older. Many dudes will settle on a female that may seem the best best for them. If she has more $$ than you, fantastic. However, when they see their friends get married the pressure is on and they apply the pressure to you. Yes, you can avoid it or get rid of her, but you will eventually have it again and again. The way you can protect yourself is what I've always said: per-marital assets in an irrevocable trust, business titled and controlled by an LLC owned by the trust (you're just the employee who draws a salary), and pre-nup with each side paying their own legal costs. Additionally, she must take your name. If she refuses, 86 her.
