I do. Others don't with me, and then at one point I simply stop bothering.

I have such good intentions.....I do talk to people but lots of my for lack of a better word "older" (i mean friends that i've known for a longer time) are now married with children so we don't go out as much as we used to.
I only mimic the actions of the other person who wants to keep in touch. If they put an effort forward then I will reciprocate said effort. If they do nothing to keep in touch then I'll do the same.
