Sounds like your are keeping busy. The emotional pain does go away with time.
The For Men Only book by Jeff and Shaunti Feldhahn is a must read for us men. I also highly recommend Hold on to Your NUTs: The Relationship Manual for Men by Wayne Levine. The 8 Bettermen tools chapters are the best things I have read for men improving their relationship.
You might want to say hi to RefuseToLose over in "Divorced But Not Done" as he too is a high school history teacher.
BTW... My son is named Neil. I have yet to meet any other kids named Neil - is the name going out of style?
