I just wanted to chime in this morning. I read your whole sitch (at work so obviously not working much). Alot of what your going through I'm going through as well (feelings, the S, etc) Yours at least seems in a better place with decent communication and her contact first. I'm really bad at DBing even after a month and a half, but the one thing that rings true out of everything is "believe half of what you see and none of what you hear" when it comes to a WAS.
The texting thing worries me. My W is a huge texter and thats how her OM started. Even now, she drops of D4 and there's always text coming in. So I say now for you to make that a boundary of yours if it really bothers you. I never said a thing.
The rollercoaster ride will continue with your emotions. I see you have really good days and then something she does brings you down. I'm sure this will continue. At one point I was ready to file a D myself and then a week later, no matter how bad she makes me feel, I want to save the M.
I really think that DBing is going to help your sitch. I think you've got a shot and I hope this works out for you. I'll keep watching and hoping for you.
