Sorry to hear about your sitch, but glad you found this site and that you are reading DR. Keep reading it and finish it ASAP. Consensus is NOT to let spouse see/read the book or this website. They are YOUR tools to get your relationship back on track.
Read the "boundaries" thread.
I strongly suggest that you do not REACT to spouse any more. Everything should be a RESPONSE.
"Puppy Dog Tails" gives great advise. Do a search on his posts and read as many as you can.
