Thank you both. Makes me feel better about my weekend. I felt so flustered about the whole thing and felt that I did horribly. I do need to throw in my 'I'm sorry you feel that way' especially when he starts to blame me for the marriage failing. Otherwise we get into the same battle as always.
Another thing to consider, when he's spewing about it being your fault is to just say well, it doesn't really matter anymore.
He wants to keep the fight going and justify what he's doing...but if he's going for the divorce, because HE'S DONE (his words) then what difference does it make whose fault it is... (I mean, you could take this attitude with him.)
