Ugh. This is all too familiar. My ex didn't let me in, to the dark side until almost a year into our relationship and I was heartbroken. He was abused emotionally, physically and sexually, but like yours, he bettered himself. I stuck by his side since day 1. I stayed through thick and thin, minus our drunken fights, we had an amazing connection and relationship. It was the booze that broke us. Now, I've been over a month sober and trying to get back what we and I once had... but reading so many posts about past relationships? I'm so close to just throw in the towel bec. it's my sobriety on the line now and I've come too far. I just wish I could get the amazing back but that might just be a fantasty now. Sad.
