What does it all mean?

I'm trying desperately hard to not go into "men suck" mode, but they sure as hell have been disappointing me lately.  I keep going back to what my friend has told me about the book "He's Just Not That Into You" and I happen to agree with her. If a guy really and truly wants to be with someone, he will.  No ifs ands or buts about it.  Being philosophical about it helps a bit. I'm telling myself that I don't want people in my life who do that and it's a good thing that I'm finally standing up for what I want. It just leaves me feeling alone and lonely. I despair of there not being anyone else on the horizon.  Of being alone.  I guess I'll just have to learn how to do single and solo and still be happy.
