Hi sh- That is nice that you have your MIL in your corner. Does she ever give your her opinion on what she thinks you should do?
Don't know how much inspiration I can give you, but even if your H acting more like his old-self and is telling people that it is over between you, it doesn't really matter. He still has a lot of guilt to process and besides that he and the orge are on again-off again. Nobody knows what the future has to hold and he isn't pushing for the D. If you aren't ready for the D, then just be as happy as you can living your life. I know how difficult and frustrating this is...but as you told me, unless you are looking to get remarried (or start the dating process to get remarried), then what is the point of persuing the D?
What would happen if you gave up without filing for the D?
