I know legally you can't kick her out and I know you don't want to leave. Then what is your next move? I know you understand that must get your wife's respect back. Your boundary has been broken multiple times you have no choice but to enforce it! You will be in limbo for a very long time because she will gladly live off you while she continues to see OM. I know your afraid she'll run to OM but sometimes it has to get worse before it gets better.
