Why is it that when you romance your boyfriend he becomes serious and in love with you?

I don't know if you enjoy the fact he is in love with you or you're simply experimenting with his feelings. People (whether they admit it or not) crave affection and loving care. Most don't want to be alone, but an instict to share their inner thoughts of their hopes and dreams with someone special. To me this is sacred ground and no one has the right to play around with it. If you romance your b/f then it's obvious to say that he could well fall in love with you and if you didn't want this then quit playing head games! When in doubt put yourself in their shoes.
