Hi, Once Was Lost! Welcome!

I, too, dealt with emotional and verbal abuse and had that "ah-ha" moment, though my timeframe was MUCH shorter (less than a year). I'm so sorry you're in this position and have had to put up with it for so long.
You're in luck because you came to the right place. Your experience is familiar to us here and we have experience, skills and tools that we're happy to share. And lots of support to give.

That's wonderful that you're excited about this and rediscovering yourself. That will be so valuable to you going forward.
I'll echo
ColdKnight. What changes are you looking to implement? What parts of your relationship are you focusing on?
