T, you are not obligated to respond to her. No matter what she said. The text exchange you sent earlier was hardly communication. I don't think she meant texting about her FB unfriendings was what she meant by #1 problem in our M was communication.
Your impulses are going to ruin you. I can tell you are a very impulsive person. You have to try to get control of that. Even in the filing for D. Are you just doing her dirty work for her? Is there any part of you that thinks maybe she is acting in this way hoping you'll get fed up and do the dirty work?
