"I almost majored in anthropology"
What stopped you? The thought of spending long days toiling in hot deserts looking for a few shards of pottery?
That would do it. I'm not a big "sleeping in a tent" kind of girl, although I love to travel so maybe that would have made up for it. I'll take a hotel (preferably with room service and pool, overlooking the ocean view) over camping anyday

Make sure you bring that up to the C."
I will, and wish me luck. I just hope the C sees that I am nearing the end of a rope.

This is why it will be important to go into it prepared so that you don't forget what you wanted to say. And don't be afraid to redirect the conversation back to something you think is important if the C is getting off track. You know what is important to the M more than they do so don't waste your time and money. Be pro-active.
I was hoping that W would like the new me better, and she does like parts. Ok, so it's not all bad. She likes parts and may start to like the other parts (sexually in particular). Have you asked her what HER expectations are for your SL? Don't let her get away with "I don't want to talk about it." You need some specifics, even if it is not what you want to hear. If she tells you she has no inclination to EVER start having a good SL that at least tells you where you are working from. Maybe she wants once a month? A week? not likely. But you should feel her out about her expectations.
