My mom wants to add me as a friend on facebook. What should I do?

[Janice]

I am 22 years old. My mother and I don't get along very well. We have had lots of problems in the past. There are a lot of things on my facebook page that I don't want her to see. For instance, she doesn't know that I'm bisexual, atheist, and in an open relationship. She would react hysterically to all these things.
My mother is very intrusive and controlling. I've tried blocking her but she keeps opening up new accounts to keep an eye on what I'm doing. I decided to open up a fake account. Within days, she sent me a friend request to my fake account. My fake account only has like 4 posts on it and I only have like 5 friends on it so it's probably not very convincing. What should I do?
