Call if you want to call!
I have a situation that is somewhat similar. My husband is a recovering Alcoholic (6 months sober) and my parents are alcoholics. My father hasn't had a drink in years and covers for mom. Well, over the years, when things were really difficult, I would talk to my parents. Mom thought I was rather 'rough' on my husband. Of course she wouldn't admit he was an alcoholic while she is pouring herself another glass of wine.
Try not to worry what others think (easy for me to say). You should just do what you feel is good for you. It sounds as though you are trying to take care of your needs right now. Keep it up.
As far as being jealous. I can relate. I repeatedly told him I was here for him. But he never came to me for help. Still when he is having a tough time, he finds help at meetings. Oh well. At least he's getting help. When things come around he tells me what was going on and then we talk. Hopefully, things come around for the two of you. But for now. Just take care of yourself!
