First, let's start with the basics of relationships....
Attraction
Alright, you are attracted to this person...but how does it go from attraction to initiating a relationship?
Mate selection
So then why does being friend-zoned happen?
Mixed-gender friendships
Why people get stuck in the friend-zone
So what to do if you are in the friend-zone?
Good luck out there!
