When u are willing to give up everything for that person even ur life then it shows u truly care and love her
It's just there in the bottom of the stomach. When you see her, you'll find out that large elephants have been there all long and start stomping like crazy
Feel ya, man.
The whole world may know you love her but only she won't. Sad story of your life. Buck up and just sweep her off her feet. Make sure to be there to catch her.
If you do stupid **** that has no real purpose then youre in love. Or drunk.
About a particular girl ?
Mate, you are in love. Blurt it out to her. ;)
I can't help, but hahah too. :)
