I've dealt with that same crap, Grey. It seems like some people think when you say yes once, you will always say yes, then they lose their minds when that fictitious belief is shattered. It's ridiculous.
Anyway, on to my vent. I feel that sometimes people just don't understand the impact their actions have on those around them. I've spent years helping someone, or trying to anyway, with things they asked for guidance on. I gave them advice, I supported them when they were alone, and I tried to keep them from following paths that would lead to worse shit than just a few lonely days and an empty feeling.
Of course, all of these failed. I wasted all that time, it solved nothing. In fact, it seems that every ounce of advice, help or support I showed was not only acknowledged and then forsaken, but simply of no interest to them, even though they asked and I did more than deliver. If you know anything about me, my advice is objective and free of bias. Of course, I hold my opinions, but I base all of my advice and other help on what is factual and pertinent to the receiver.
I said something that I couldn't get out of my mind when it came about. "The impenitence of some is the suffering of many." While I shall remain this person's friend, I feel nothing short of apathy to their actions. I have respectfully asked them to just not include me, whether by informing me of or otherwise pushing me into it in any way, and we won't have a problem beyond this. I am willing to look past it, no matter how much it hurt to see all my efforts come to naught after so long. It is their life and these are their choices, and if they do not wish to accept fact and follow it... very well.
Sometimes I surprise myself in my ability to bounce back, because after a long drive after work, with nothing but the wind and music to accompany me, I feel alleviated entirely of the stress and anger I felt previously. However, that doesn't change anything about the situation, as much as I would love to believe it does.
