First of all you can't blame everything on an MLC. From what you described, there are many things that are just part of being married.
"-It really went downhill in Jan 2014 when i started a new job and became super stressed out -March 2014- H decides to completely and utterly change career paths (he went from a financier to an actor)"
Nothing wrong with a career change. If he wasn't happy, then it's within his right to do what makes him happy. It's his career after all.
"-March-July- we are stressed, not connecting. He complains about Sex life (well I take it as complaining and nagging vs. listening for his true needs)"
Caused by lack of communication skills.
"-On our anniversary in July 2014, he says, if we're not pregnant in two months there's no point in being married."
Did you want to have a baby?
"-that was a bomb drop to me and i seriously questioned if I wanted to be with a man who didnt care about my needs."
From his perspective, the same could have been said about you.
"-From that BD, the crap just hit the fan. I was completely withdrawn and didnt feel safe around him."
Why? Because he wanted a baby?
"- He also wasn't getting what he needed from me."
Which was what?
"-We went to counseling in Jan 2015, but at that point, I think he was done."
Who initiated? What did you go for specifically?
"- I moved out in June to give him the space he wants"
Did he tell you to move out?
