The last chance to salvage a broken friendship

I am a high maintance friend.  There is no doube about that.  I need to see my close friends frequently.  I get tired of people who I have to call many times over to get a hold of.  I grow weary of the hard-to-obtain.  There has been only one exception, and that was Will.  His girlfriend has been falling into the same pattern as him.  I will not make excuses for her anymore. 
I decided this a week ago. 
I called her tonight, after not talking to her since the first, and she has not called back.  The message I left said that this was my last attempt at salvaging what friendship we had left.  Will doesn’t understand just how much he’s losing me.  I’m tired of both of them and their stupid games. 
He promised me when they started dating that he wouldn’t blow me off for her.  He didn’t keep the promise.
He told me that he’d call me last night to let me know what was going on, or if nothing was going on.  I haven’t talked to him.  since, and I’m sick of waiting for him. 
I’m tired of losing my friends to relationships, and I’m nearing the end of my rope.  So fuck this, whatever it is…
I’m tired… I’m sick of this bullshit, and right now I just hope that they realize how much they’ve lost me and I hope that it’s worth it to them.
assholes.
I don’t have compassion for them.
