I've got a question tickering in my mind. If you love the person, would you do by all means to make her happy? Wouldn't you try to amend all your ways to consider and care about her feelings? In this fast-pace and challenging lifestyle that we're leading to sometimes brings lotsa complications to us about the people around us. When your promises are taken for granted, when your existance seem less important factor to the other party. When your patience are always put to the test, when you don't belong to his priority list, when you know his capabilities. When he just wouldn't listen.
I'm sure this isn't the first time it happens, I'm sure lotsa people have experience this, ladies or gentlemen. But it all sums up to the same, if your other party loves you or have some other intentions behind it all.
If you don't like to be played with, why play with other people's hearts. If you can't handle your own life, why try to take charge of other people's lives? Be responsible of your actions.
Humans are born with brains to think. With age to experience and understand. So if you've done something wrong and you end up in the losing end, then don't try to persuade the person to stay, worse come back. Learn from what you've done, don't try to make up for hurtful situations that you've cause, it'll just make the person more agitated. If the person says she doesn't like it, then stop whatever you want to do, scrap whatever you have in mind.
Don't treasure the person when she's gone, treasure her when she's there.
