Sue,
I always tell parents what you hope for is what you hate. You want him to become independent, but it is the independence you hate.
Always keep in mind there are ton's of families where their kids have selected the wrong school, for whatever reason, and they are facing kids who are homesick, kids who are involved with drugs, alcohol, parties, and some are even becoming parents. How does the saying go, "I was feeling sorry for myself because I did not have any shoes until I saw someone who did not have any feet."
When Brian was a Freshman I wanted him to call every day, unfortunately he didn't.
I was able to convince myself it made more sense to make an agreement with him on a day of the week. We chose Sunday night, and if he could not make it, he would call us and tell us.
Our communication has been via cell, but if I really need to speak with him I txt him. Basically I have "Call Me ASAP" saved in my phone and send it to him.
Today's kids don't seem to use e-mail.
The bottom line Mike is becoming an independent young man, and looks like you have done a great job inasmuch he seems pretty confident and is handling most issues on his own. You should be very proud.
Hope I have helped!
