Husband said I always put my sister before him

Me and my sisters dad died when she was 10 and I was 13. So my mom worked 3 different jobs to keep us afloat. So I cared for my sister. I practically raised my sister and I'm basically her mom because our mom wasn't around and worked 7 days a week. My sister is 27 now and needed a place to stay for a few weeks because of a mess she got herself into and she knows she can always count on me. I will always be there for her no matter what time or day. My husband was annoyed that I moved her in and said she's a grown women. I told her she's my family and I've basically been her mom and my husband said she has a mom who she can go. My husband and my sister don't get along that well. Me and my husband were supposed to go a vocation to Florida and he asked was it still happening or was he gonna be put on the back burner for my sister again. I told me that it's still happening and I had every intention of it happening. We are supposed to leave tomorrow but yesterday my sister's boyfriend broke up with her. They've broken up a few times but this time he's completely done with her. And he's taking their dog. She was bawling and said she didn't want to be alone and I told my husband we had to cancel. He got upset and said I always do this. I said I have to be there for her and again explained how I raised her and was a mom to her. He told me "You aren't her mom! You didn't have an absent mom! She was working! You have a mom and the only reason your sister comes here instead of to her actual mom is because she won't enable her bullshit." He said every problem my sister has ever come to me with is a problem she gets herself into and that I baby her. My husband ended up leaving because he couldn't deal with me. I've been there for my sister and trying to talk to my husband but he said he's not coming back until she's out of our house and I stop moving her in. I never want to choose between my husband and my sister. I thought about calling my mom to ask for advice but her advice will be biased anyway because she's not happy that I claim to be my sister's mom. I just want some non biased advice.
