BIL is going to ride it out in the hotel, at least for the time being. SIL is distraught b/c she wants to go take care of him or have him come home but that would expose her and baby plus it would mean he'd have to re-do the whole month-long training next month, prolonging their time apart.
As for the step-by-step approach, again, it reminds me of high school, inching toward it bit-by-bit and being comfortable staying at each new plateau for awhile. It may sound strange that I'm not chomping at the bit to 'go all the way' but I feel so loved and cared for that I am content and happy. The journey is so pleasant that I'm just not fussed about the goal.
And, as many here have said, it took a long time to tank our M as badly as we did, so not rushing things is the way to go. I'd rather slow and done right than fast and stuff bites us in the arse later.
