Shorten the email, get rid of all the I'm probably just rambling stuff, get rid of I don't know if this makes any sense. DO NOT marginalize yourself and your feelings. You are so bitchin' don't sell yourself short!

How about:
So it sounds like the first week of Oct is the soonest you might return, or it could be several more weeks, or maybe months? You asked if that's okay with me and/or if prefer it?

I can't think of a particular reason right now why I would need you to come back by a certain time. I do want to get away for a few days in Oct, but I can get someone to watch the dogs if you won't be here.

As far as prefering that you stay over there longer, I don't really know how I feel right now. I really care about you and all that, but I have to say that the time apart has been good for me. I feel like I'm rediscovering parts of myself that I lost touch with these past few years and like I'm getting back to the woman I used to be, in a good way.

Things are good here (or positive phrase of your choosing about you and your life)

Best wishes,

Dudess
