Sorry to read your hurt feller.
From what you describe above, this person seems to have multiple personality flaws. Fairly serous ones from your description.

IMO, Read your own words and believe them: "I can tell you now that I am much better off away from a compulsive liar and a controlling [] who does not know how to treat a person with respect and decency " .
That's your own summary.
Map a new course, turn your sail into the wind .
Bon voyage Captain
