Feel like im nothing in my husband's life?

[Laura]

The 3 of you are living together? Who's house is it? How does she need to be taken care of?
The answers to these questions will determine some of my suggestions; however, I would agree to ignore her. What she said was an evil thing to say to anyone regardless if it was true or not. She sounds like a jealous and sad women. I would petty her. Be polite and limit your interaction with her. This sounds like the typical mil and daughter fighting over the son/husband. Really don't waste your time. No one wins this. Remember he married you but he grow up with her and it is NOT a Competition. Protect you marriage by being an adult and a wife, don't fight with her. If your husband will not stand up to her, by saying please respect my wife. You may be in big trouble.
This is common problem!!!
