How are you supposed to trust women today when women give so little?

Pretty straight forward question. Most guys will know what I'm talking about. I don't think women realize (maybe they just don't care) that 90% of a guys effort is wasted with women. Decent men don't go into a relationship with the thought of failure. But the majority of women only entertain the guy until something better comes along (in her mind). So a guy knows he'll be working hard trying to build something only for her to just end it seemingly out of the blue because she finally met what she really wanted. And then he's back to square 1. Understandably, after a while the guy doesn't want to to start over anymore so he is unwilling to put forth only the effort she is. Which we all know women are unwilling to do as a rule.
