I normally stay away from giving relationship advice…but I agree with everyone here…run! You got out of an almost two decade long marriage, you don't need this drama in your life. While there are emotionally healthy women out there, many in our age group have been in multiple unhealthy relationships and you are inheriting someone else's baggage. This isn't a fixer upper relationship and you don't have much invested in it…move on, you can do better and live a happier and emotionally stable life.
