falling is the easy part ......staying is the hard part..................
in no time or forever
It varies. You really need to get to know someone and talk to them before you realize you've been "hit with the club". My experience is that there's a lot of people that are desprate for all the wrong reasons and just want to jump into a relationship because they just want another person in their life because they feel they have to have somebody or feel "less than" because they don't.
It took me at least a year with my ex and current partner , to fall in love .
It can vary from 1 sec to a lifetime... There are some who see someone and fall in love - called love at first sight..and there are some who live with someone for a lifetime and when the other leave, they realize the ache in them as love..
a split second...just takes awhile to realize that's what happened.
