49
Both sons moved out within 4 months of each other. Wasn't ready for younger one to go - was only 20 & not married. Older son got married & moved out. Both are now married - 1 for 13 years & the other for 11.
I wasn't as upset about becoming an empty nester as I thought I would. I guess I just thought it was time for them to spread their wings & try new adventures. Besides younger son only moved about 5 blocks away from us! :-)
