Under...It is obvious you feel like you must do things to appease them and not make life miserable....but, from your comments...you sound like you are not real fun to live with right now because of your unhappiness. That is what your kids and wife see. A grouchy guy, hatin life......Let them see you free and happy. You can come home early on meeting nights and PLAY with the kids till the last second when maybe they'll get ready for the meeting...and YOU DO NOT HAVE TO....maybe someday they will stay home with you, seeing as you are so happy.
SHOW YOUR FAMILY YOUR TRUE HAPPY SELF...BY FINDING THAT SIDE OF YOU!!
