Thank you all for the responses. They really do help me. I'm trying to absorb this all in to understand better.

She is flying to see me today. Her flight gets here in 7 1/2 hours and she'll be here until Monday.

As far as telling Mellisa about conversations with Lisa, she has made it very very clear that I need to not do that and that it does more harm than good to do so.

I also want to say that I'm really glad I found this place. I think I would have lost it over the last few days if not for some of the supportive people here.
