Also, it is possible your W's text does not require a response. If she texts again, as a question, you might respond letting her know simply that you agree (IF you DO agree), and leave it at that.
As far as FB, good that you eventually logged her account out. It CAN be tempting. Also, disregard her comments. She's either saying what she thinks her friends want to hear, or just venting.
Keep doing what you need to do regarding the D paperwork and also, keep working on yourself and your positive changes.
