What is there to save? From how you describe her she sounds like a nightmare and it sounds like the two of you really had your fair share of troubles. Why *would* you want to save that? IMO EVERYBODY (who cares to try) should not be saving their marriage but tossing it in the trash and rebuilding something new (who knows what the new would be?). Nobody wants to save something that caused them pain and strife. But you will be associated with pain and strife in your W's eyes for a long time (and vice versa of course). But what are you doing to ease that? I realize she is doing very little but what are YOU doing?
Let me ask you this... do you want your W to come back just so you can reject her because she has rejected you? I sort of get that vibe from you... if somehow that happened you would find "peace" in having the final say.
