So the decision has been made - Carol and her "bunch" are moving in come early June. Over the last few weeks (and several discussions on the topic with their her), her kids have gotten much more comfortable at the house and the idea of us all living together. I had them over for dinner yesterday and I could tell that her D18 and S16 were much more at ease and felt at home. It's going to be a busy couple of months getting ready for this, but I'm all in 100% and happy with the prospect of merging these two families.
Of course there will be a bump or two (heck maybe even three) in the road, but everyone is being very transparent, open and positive regarding this so as long as we continue to listen to each other and not let things build up I think we will all be fine.
