My stance from the beginning has been that I don't want a divorce, this was her decision, and she can handle it herself.
I know that it has happened when a LBH has filed and that has caused the WAW to face reality and reconsider, but I think your sitch is still to early on for that, really.
Take my advice with a big ol grain of salt, too, cause I'm in the throws of this myself and am making mistakes.
I haven't fought with my wife about the divorce. I've always told her that shes gotta do what shes gotta do. I told her that if that's what she needed to do, then fine, go for it, I'll sign the papers and I'll be fine.
Now, give me a few more months of roller-coaster and I might be singing a different tune and file myself, And be done with her, but for now, the D is on her and her alone, and everyone knows it.
I think giving into her and filing, even if you really don't want to, and are only doing it because she talked to you like that is actually the exact opposite of "manning up".
