<human>: Can you give me a shortened version of the text?

I'll try to make this short. My husband is oldest of 10. Most of his siblings are "adults" and shitty ones. We spent $850 to fly his 14 y.o sister out to his and her grandparents, which is where we all are now. I like her enough when I can get past her angsty mumbling. She literally wants to do nothing all day and interact with no one unless forced, which is fine, but I personally find her attitude borderline disrespectful.

Anyway, today I was sick, visibly, and I was kind of pissed bc my husband seemed too occupied by whatever he was doing to "take care of me." I don't want to sound like a dependent pansy, but everyone likes to be taken care of now and then. He asked if I needed him to get anything from the store and brought the laundry in and put it on the bed. As he was walking out he asked if I was okay, to which I said yes. I spent basically all day in bed or on the couch, but other than those encounters he did not acknowledge me.

Fast forward to later this afternoon. His sister doesn't want to leave her room (like every other day) and all of a sudden she is sick, too. Well howdy do, if everyone, including my husband, didn't fucking jump up and start trying to nurse her to health. They were finding crackers getting pills and his grandfather made a trip to the store to get stomach medicine. My husband specially took all of this in to her, made sure she took it, and said "love you" when he left the room.
I won't deny that it's jealousy, but I think I am validated in feeling the way I do. Where was that concern and attention a couple hours ago when I was sick? Am I crazy here? I said something to my husband and he just thinks I'm blowing things out of proportion and almost made it MY fault that I felt this way. But that is a reoccurring theme with us I feel. If I'm upset, it's either me misinterpreting something, me pmsing, or just being irrational.
<bot>: Husband jumped at the chance to take care of sick sister, but didn't care so much hours before when his wife was sick.
