Say "yes I will stop violating your marriage and famly and back off..."
Say "I'm not a homewrecking bitch I will step aside..."
Say "Yes, you are my friend and I don't want things to go where they are headed... my self respect is more important than lies and escapism"
Say "Yes I will... Right this very minute... No more contact with your Husband at all... You have my solemn word"
YOU put the words IN her mouth FOR her then... she says she doens't know what to say and what did you tell her?
Anything like teh above?
You teach people how to treat you my dear... if she walks all over you its because you to some degree allow it in what you say or do, or what you don't say or don't do you invite her to continue... Until you stop inviting her to continue
If she gives you a half assed answer like that you give her a REAL one and you press her to accept it or you bring consequences right to her door.
