So my husband called me a fake and a phony.. why?

Everytime my sister calls me I listen to all her problems. We stay on the phone for hours just talking about her problems. We never really talk about me... So I'm not selfish. I give her advise when she needs it ( Almost everyday). My sister called me yesterday around 10 pm and I told my husband that I'm going to take a break and make time for myself. He called me phony and fake and that I should be there for my sister. I broke down because that's not even true. Just I didn't answer once or twice... I'm considered as a bad person. Why do he care so much?
