Just a vent...

Ever reach that point with some long distance friends where you realize if you never e-mailed them then you wouldn't really have a friendship? I have 2 friends now that I realized are not worth my time anymore. They never e-mail me out of the blue, I always seem to be the one to do it. It just isn't worth it anymore. If they don't have the time for me why should I bother? So, I've made a decision to stop sending the "hey, how are you doing, haven't heard from you in a while" e-mails. I actually made this decision a few weeks ago and still haven't received any e-mails from the 2 in question. So, maybe it's better to just say goodbye and move on. I don't really want to do this because I was good friends with them in college but I sort of feel like this is one sided. Like I care enough about them to keep e-mailing them but they don't ever write to me unless it's a reply to my original e-mail. So, here I am saying goodbye to them. If they e-mail me in the future that's fine, I'll respond but if not, I refuse to go chasing after them anymore. Does this happen to anyone else? (I'm not really sure who I'm asking this question to, since I know there are only a few people that read this blog, but even if you are just a passerby, respond...I'd like to know if I'm the only one that has gone through this).
