My husband works a part time job for "fun" in addition to his regular full time job. He took 2 days off this last week to help his mother. She has not really been a part of his life since she chose her boyfriend over her 2 oldest sons. I have had very hard pregnancies the last 2 children and this one is proving to be the same. I told him I was not feeling well and he said "oh well" and went to work. He has to work a 9 hour shift today and wont be home until after I have put the kids in bed.

Update: This is a new behavior for him, well with the job anyway.
