I thought you probably meant "move forward". Wow, your kids are always going to parties! It sounds like being a kid in Greece is a lot of fun. Playing it by ear sounds good.
It sounds healthy to think about prerequisites because you probably already have them deep inside, even if you haven't articulated them. Maybe you could start with what seems too obvious to need to even say. From what I understand we're so eager to have our Ss back that sometimes we forget about our own needs. I have read that when the S does come back frequently the LBS's issues start to come back. So to have that expectation and think about it and prepare for it ahead of time is probably very helpful and healthy.
I think it is also normal to feel passive about progress sometimes. It is such a rollercoaster I think our emotions don't always act as we expect them to, but that doesn't mean anything is wrong inside.
I know you think your H is slow, but from my point of view it seems like he's moving at a Medium pace! you know, even if the speed was up to you, I think you are supposed to Go Slow with the R no matter what, otherwise the WAS can get scared and freak out. (like if this weekend you went through the sex positions calendar , all the pages for the months of january and february, he might get a little spooked). So you are lucky that you don't have to slow down your H, b/c he is already Slow Enough!
It is better to move slow and steady, than to have lots of confusing rapid returns and alarming departures, right? (which seems to be a pattern esp for MLC WAS)? So slow... like you said... what was that thing about slow honey?
