I let people fall in love with me because I like the attention.
Is there a reason why you care what people think about you?
It makes me feel like I'm important when I'm the object of another's affection.
It's understandable that you would enjoy the attention from someone. If you aren't interested in them though you should do your best to be honest with them about your feelings.
Love is just a game to play with someone else's feelings. I only care about me.
Well, you can only play that game for so long. It's very unkind to lead someone on when you're not interested.
