friendships SHOULD definitely be two-way. you should not have to always be the one to contact them. however, hamster is right, sometimes people are really busy. I have a friend who I know it's not one-sided, but it's usually me who contacts her -- but then she has six children at home that she home schools...she's very busy.

I have done things to "test the waters" with "friends" and have found some very lacking...even ones that at one point I thought were REALLY great friends.
