Disloyal or am I losing it

My husband and I were staying with my sister and one day she told us we had 24 hours to get out know we had no money and no where to go... So she basically threw me,my husband,and our son out in the streets. I'm also 5 months pregnant. I no longer talk to her and honestly I never want to again but my husband never got mad at her for throwing us out....She also invited him but only him to move back in... She is also married with 3 kids so I know they are not cheating however he still talks to her everyday and I feel like that's inappropriate and so disrespectful... Am I wrong???
