Help a momma out

This b*tch is tired. I love my 6 month old to death but she's attached at the hip to me and I need a break. I'm a SAHM so I get that she's going to prefer me over dad but he can't console her at all. He will do everything I do and she just cry's. We've tried the CIO method but she just doesn't stop, she just gets worse. When he's home on the weekends he lets me sleep in. Awesome! But as soon as I'm up, she wants nothing to do with him. She will hardly drink her bottle with him. It's very frustrating for dad and I. He wants to help and feels bad that she prefers me and I need a break. I can't even go to the bathroom without her screaming bloody murder. It's gotten to the point that I can't get anything done during the day unless she's sleeping and then it's hard because I have to be quiet to not wake her. Anyone have any tips or tricks or advice for me or dad?
