Is love a choice? I know a lot of people who would argue that love is an emotion. My dad has always told me that lust is an emotion, and love is a choice. I didn't always agree with him, but first hand experience has changed my mind.
Emotions don't make me love him when he's feeling depressed. Emotions don't make me love him when he's moody and upset. It's during those times that I choose to love him still, to listen and talk and help him work through it.
Emotions don't make him love me when I'm in a bad mood. Emotions don't make him love me when I'm being irrational. Emotions don't make him love me when I've been too busy to talk for over a week, or when I'm going so fast that he doesn't even know what city I'm in. But he chooses to love me still. He chooses to let me rant. He chooses to let me cry and then tell me how much he loves me.
If I let emotions dictate our relationship, I might have given up when people I trusted said that we would never last. When my friends turned away from me. Instead, when one of my friends told me I had to choose between him and her, I made my decision. I choose to love him.
