[Red Hope]

What actions should I take next if she pulls another stunt like the other night. I don't want to be a snoopy, control freak, but I want to make a stand and hold my ground. Looking back in the past I have not done this! I was talking with my W sister about everything about 1 or 2 months ago and she said I let W get away with alot of stuff. I have become a push over to W, and I really need help with ideas to help be a stand up H with action to W childish behavoir, with out being a snoop or control freak.
