She wants to run away with you, send sexy texts, hump like bunnies. It doesn't sound like either of you actually reset, time away is what was needed, to reenter R building from a healthy place, you skipped that part.
For what its worth, my ex and I had a sex marathon, she was saying she wanted work on us, going to counseling, etc.. right up until I found out she was downloading "NoTraceIM", "Whats App" and another one I don't recall. I decided I had enough and ended it.. Then about 6 months later I understood what it meant to have space and recenter ones self.
Good luck Jim, I hope it doesn't turn out to be the mistake I fear it might be.
