Love is a drug
That's true! I've been in a few relationships and I know that love really is a drug. It can makes you feel good when you have it...sometimes it gives you bad feeling.
However, I do not really fall for the latter effect. When love tends to make me feel uncomfortable, I just stop it. That's the case for my previous relationships. I don't really have problem with ending a relationship as long as I believe it doesn't worth anymore to hold it.
Life is meaningful and the best love only goes to the best lover. Not everyone is the best lover. At maybe some point in time you think a person is the best one, then for few years later, you realized that you were wrong. Well, just don't buy into stuff so prematurely. Use both heart and brain. Only the best person deserve the best of my care. And when I settle down (cough cough... In a very long time), there will be and only one who stays beside me forever.
