This is the one and only proper way to vent a woman for marriage:
1.Dating casually
2.Relationship
3. Living together
4.Engagement
5.Marriage
She has to prove from 1 to 4 that she is worthy of marriage. Not only will simple time be a factor , because of the infamous shelf life of relationships. Most relationships deteriorate after 2 years, and by that point you are probably in stage2/3.
If a man is honest with himself and willing to cut his losses he won't take things to the next stage trying to fix a broken relationship. Lotta men think that a deteriorating relationship will get better when they promote a bad behaving woman. Its similar to a gambling addict refusing to cut his losses.
She must think it's her idea. So marriage imo,means she behaved properly for more then 3/ 4 years, making it HER idea to stay loyal to YOU. By the time you marry her you should've felt the pressure of having a great and trustworthy woman on your side.
I also wanna point out that at stage 3(living together) , you will get to know a completely new side of her amd vice versa. So stage 3 is basically a reset. Stage 1 and 2 don't matter anymore once you enter the third stage.
