My bastard Father blocked me on Facebook.
The backstory to this is that he abandoned my DM and me when I was three. I didn't see him for a good twenty years. I plucked up the courage to send him a message on Facebook. He responded and answered all the questions I had, (Feed me a cowardly pack of lies blaming my Mother). Then we arranged to meet, for the first time in twenty years at a neutral location. It was my suggestion to meet.
I thought it went well. We got on. I then messaged again a few weeks later suggesting another meet. So we did that. Then, I decided not to message again because I didn't want to seem to pushy. I left it for him to do as I'd arranged the previous meets.
Several months later I'd heard nothing and I see he's disappeared from Facebook. I messaged my half sister who I've never met, but we were friends on Facebook and my Dad had said she wanted to meet me. I asked her if he had deactivated. She said he had. Few days later I realised that was a lie and I had actually been blocked. So I messaged her back and said, 'he didn't deactivate did he, he blocked me'
Then, she blocked me too!
So, my cowardly Father has now abandoned me twice. Full of lies and cowardice. 
No AIBU. Just a rant.
