This mentality that time spent in a relationship equals an investment that desperately needs to recouped, no matter what, gets so many women into trouble. It's not always the things that people like about one another that keep them together---sometimes its unhealthy emotional codependence, lack of confidence in ability to find something better, low self-esteem that leads people to thrive off constant conflict and drama, etc. And even things you did like for whatever period can be far outweighed by the negative. A good relationship should never be about constant conflict, drama, hurt... a good relationship brings out the best in both people.
Any wise investor can tell you that sometimes you make a bad investment and its best to just cut your losses.
