Good luck with the move. I sold 2 homes and bought 2 in the past year and half. Moving, moving, moving - I should be a Pro by now. It is NOT easy. Or Fun but the results are wonderful.
I sold the marital home after hanging onto it for 5 years on my own. It was very freeing. The fresh start is wonderful. Good for you AND the kids. Now I've moved to my dream location on a lake with new man although we still do the long distance thing as he works in the city Sun to Thurs. Hang in there. Fed Ex guy sounds good for you and the long distance thing can and does work!
And hold on tight to the memories. Many of them Were good. Deny them and you deny your kids' childhood. I'm still working on this part. Hope to watch home movies again someday soon.
