Is it normal?

Is it normal for your husband ex girlfriend is always talking to your husbands sisters & mom? But they rarely talk to you??! My family different. If my brothers & sisters broke up with theyre SO. we dont talk to them cause its kinda disrespectful UNLESS. Theyve had a child from the SO. But i feel like im not in the family she is. They always talk shit bout me. But never actually spend time with me. But they want me to watch their kids, babies, clean , help them move. It just feels like im their maid not their family.
