WTF?

I thought I had made a friend.
I thought the enjoyment was mutual.  I had someone I really did NOT have to invest in emotionally.  I had had a couple of messages saying that he was having some difficulty and could not make an appointment with me.  I said that was not a problem and offered to be supportive. I was doing my damnest to be sincere about being supportive since I do not understand the emotional issues.  But, I am always willing to listen and simply be there.
Days went by, no word and I worried because, well...I understand from others what happens when one gets depressed.  I did get a reply eventually that said he was ok.
More days go by.  I wonder, but I believe in giving space and I did not want to sound naggy or clingy.
I sent off a few more text messages. 
...and more.
and a few more after that...that I thought would be seen as humourous.   No word.
A new month started.
No word.  I send off a note to his 2 accounts.
A couple of weeks roll by and I check again to find out both accounts are gone. 
Gone, like they were never there.
If a person is done....if they do not want to see me any more........fine.  Tell me so that I am not sending text after text.  Give me back my house key.   Man the fuck up, and let me know so that I don't waste any more of my time on you.   To just up and go away is just rude.
I trusted you enough to give you a key to where I live.  I asked nothing in return except some respect.
You disappoint me.
I, am done with you.
