I"m staying at my ex's house this week- the house we were married in 

I'm fortunate that I have an ex I get along with most of the time.  But I do believe I'm going to be testing it out.  My family has had an emergency in my town, and I now am the only one that still lives here.  So they are descending from all across the country and there is a good chance my house is going to run out of room.  So the plan is if that happens, my kids and I are planning to go and stay with the ex.  Now for my kids, that's no big deal.  They stay there 3 nights every week anyway.  Or maybe it will be a big deal.  The last time their Mom and Dad shared more than birthday cake together was before they can remember, let alone a roof!  Perhaps he'll just let us be and go off with the girlfriend and stay at her house.  But even so........how strange is it going to be staying in a house that I haven't lived in for 10 years, but once loved and adored and even brought my children home from the hospital to.  Talk about going down memory lane..........anyone else ever do this one?
