You aren't going to get remorse until she really really feels she has lost you for good...
And boy do you get remorse then... Read up on the women that really really feel they have lost their man on this site... Notice the remorse. It is all because of losing something you may not be able to get back. That is what stirs the feelings. As long as a woman knows you will be there for her just about any time she wants you are destined to keep spinning your wheels... Another three years, four years, etc. etc..
You don't have to be mean. You just have to be firm that you havge had enough. No more. I WILL find a woman who treats me well. There are plenty of fish in the sea... When yo do that you will be on your way. Until then, you will struggle.
