To be really direct with you hun, there seems to be this expectation of what love FEELS like.
Maybe it doesn't feel as you think it might.
I am fairly positive this linking love with emotions is a fairly modern concept, it developed in the last 100 years.
Similarly, 'romantic' love (especially as related to marriage) is about 400-500 years old.
The hormone thing is over-rated as far as love goes, seriously, that isn't what it is about. That is animal stuff, the human equivalent of a bright red butt.
