Good to hear that you have progressed towards meeting someone who can appreciate you and help you open up to being more positive about yourself and your life. By doing this you can begin to learn what you had missed in your relationship that you may have not realized before. Could be you were actually unfulfilled and just didn't know it, it's important that you allow yourself to find that out instead of obsessing about how your ex wife disappointed you and let you down. It's like wearing the same sneakers for years, somehow losing them and feeling really upset but then you find a new kind of sneakers that are WAY BETTER and you finally get to a point where you say, damn, glad I lost those old sneakers cause this pair is WAY BETTER and I would NEVER go back even if I could.
