The writing is on the "wall"

I have this theory that Facebook is the root of all evil, especially when it comes to relationships.  I went to H-2's page today and saw a post that read "Hit me up Friday, I know a spot."  This was posted by a friend of his that we both went to high school with.  This guy is a known player and cheated on his ex-wife.  He even tried hooking up with me before I was with H-2 and when he was still married. 

So I say to H-2, "I see you have plan for Friday."

H-2, "Huh?"
Uhhhhh......yeah, I guess I forgot I was born yesterday. 
He has spent the better part of that last hour telling me he didn't contact him and he had no plans for Friday night.  He then spins it on me because I have a friend coming in from out of town who wants to go out for a Girls' Night.  I asked on Facebook if anyone knew of a place to go dancing that had an older crowd. 
Well that just screams cheating to H-2.  I am going somewhere that is a "club" and serves "libations" (who uses that term anyway?) and what ever goes on afterwards.  OMG!!!!!!
Can he get anymore annoying?  From day 1 he has been paranoid about cheating.  In the beginning I got it, his ex-wife cheated on him and left him for the man she cheated with.  She has since married the guy and had a child with him.  But thanks to her actions I have spent my whole relationship under this huge microscope.  I had to get rid of all my male friends because he wasn't comfortable with them.  I could absolutely under no circumstances speak to any of my exes who I was friends with.  Not even when one of them had a baby and the baby died after only nine days in this world.  Sending him a condolence message on Facebook was like stabbing H-2 in the back. 
When you come into a relationship and put that much pressure on a person its only a matter of time before that person cracks.
