Take the D filing with a grain of salt. Mine did the same thing. She filed without telling me. Well, actually she said she wanted to talk about it, so that evening we talked about filing D or just separating. She basically let me talk for 15-20 minutes about why I thought we should try a trial separation first. Then she quietly went into another bedroom and that was the last she ever slept in the MB. Turns out she had already filed before our talk. She just wanted to hear what I had to say anyways. For what its worth, she never served me.
Divorce can take a long time so ignore the fact she filed until you get served, then give it to your L and let him/her know you are not in any rush.
