Had a conversation with S18 last night - it was the first time I had a chance to talk to him since I heard W told him she was moving out. Conversation went like this:

TDR: Mom told you she rented a place and is moving out?
S18: Yes.
TDR: This isn't what I want - it was her decision. I thought there were other things we could do to work on our marriage before this happened but she isn't interested.
S18: How can you afford 2 houses?
TDR: We can't really, but I am going to hang on to our house as long as I can.
S18: Then why can't you tell her she can't go?
TDR: She is an adult and can do what she wants.
S18: Then she should pay for it.
TDR: We are sorting that out now - I think she should work more to help pay for all this and she wants to be home for you guys.

TDR: As far as where you would live, you are 18 and can decide to stay wherever you want, and even D16 might be able to do the same

S18: I am not going to be moving my stuff back and forth so I am staying here.

TDR: but S12 and S11 have to go every other week to each house

S18: Why?

TDR: It is something that is court ordered and not up to them.
