The way I see it is you try to keep away from D as long as possible correct? Two reasons, one to work towards reconciliation or two, you become okay with the D because you've done the work and detached.. This is not to say it won't still hurt, I am sure it is a sad day/ week/ month...whatever. But at least you have tools in your arsenal to deal with it.
Drinking is not your friend, Andrew....in my case it makes me miss H like crazy and I contact him and ...well, you know this does not end in DB textbook style
I know you want a place with the kids, but are you guys currently juggling days? If not a small taste of upheaval,never hurt anyone..in my switch, H is beginning to realize that all the things, all the places were as a family and he is beginning to feel the ramifications of leaving.
