Oh geesh..I know this feeling well! My oldest son moved out a little over a year ago when he was 19. We butted heads and argued over everything when he was home and I swore I would dance the jig when he moved out on his own. I bawled for 3 days after he left! He moved just over an hour away, and comes to visit, but not as often as I would like. My 15yr old son also just moved out in September to live with his dad for awhile. He was missing his dad a lot. Now he's over 4hrs away!! I miss him so much too! Just me and my daughter now (7). It can get lonely sometimes and as much as we complain about how these kids can drive us batty...it sure is nice to go batty occasionally!!
Your son is growing up! What an exciting time for him. You must be so proud! Good job mom!!
