I think dolphin has a very perceptive possible view of your dream. And perhaps you are right, and you are accepting the inevitable. But here's another take:
IF she was truly the love of his life, would it have taken 15 months to file??? Perhaps the significance of the dream is that he feels as if he is constantly running to catch up, and is losing both of you in the process. She may have presented him with an ultimatum after all this time, and he feels he has no other choice.
Personally, if I met 'the love of my life' as if there were such a thing for most of us, I'd want the rest of my life to begin immediately, not 15+ months later while I thought it over.
No, Seeking, I don't think you need to 2nd guess your perceptions up to this point. OW may still be driving this train for H, but you are definitely not a passenger.
Think of it as having one less person to worry about. Now, you can concentrate on just you and your children. Emphasis on the YOU.
