Don’t call him everyday – It may from time to time seem as though the male half of the population hasn’t fully grasped the concept of staying in touch but trust me we know how to call you when you haven’t called us.
If you call constantly to “just check in” then the chances are he’ll feel smothered within a week and will lose interest or just assume you are a bit desperate.
Retain a bit of mystery and avoid sending him a friend request until you’ve got to know each other better. Pay attention to the introductions – We guys are extremely territorial (even though we may not know it) and once we’ve come to the conclusion that this is the woman we want, we’ll start saying things like “This is my girlfriend, Sarah”.
Once he has started calling you his girlfriend, babe, woman, or even his other half, he won’t stop.
This is a bit of a subconscious thing with men, and although we think we want to spend the night at your place after a first date, in the cold light of the morning after we will be relieved that it didn’t happen.
