Having read the majority of the posts, my only real comment is that "sacrifice must be appreciated by both parties".
My children started a new school this year and up until last week, my husband couldn't have told you what time they started or where to drop them off.
Probably drop me a text or two. My question is, my 30th birthday weekend is coming up and when I mentioned it to him he informed me that an old friend from college's wedding was that weekend and that he wanted to go.
All this said, God is love and fully understands and appreciates your problem.
