Interesting on the reading there, and useful to look at things in a more compassionate way. I think it you feel really angry, it's pretty hard for that not to become evident to your S in some way. If you can genuinely get to a place of feeling some compassion, it's so much better - for you if nothing else!
I found reading stuff about MLC useful for kindness. The descriptions of the MLC stages on the Hearts blessings website were useful for me. and I certainly feel there is an element of MLC in our sitch.
The other thing to remember is - whatever is causing your sitch - your H isn't in a good place atm. Being a WAS is not a great place to be. We hear that from WAS's kind enough to post honestly about their experiences on the forum. Like Sandi...
