Dear Egg,
It's very chicken & egg, & depends on an individual's
opinion. Some feel that it's better to know you can love a person
before you start wooing her, & some feel that when you're
chasing a person, through interaction, you'll know whether or Not
you'll love her.
Go with what you feel is best for you, & the situation you are
in
Nobody gets it
right everytime. I got it wrong so many times before I finally did
it right
