Dealing with a WW trying to save marriage

[SoTorn]

I think that she may have retained an attorney and is trying to get me to agree to mediation. Should I just go through with it if she does?

I don't want her in the house but I don't think I can qualify for it if I buy her out. I would have to refinance it for its full worth, which would give me about $100K in equity split between us. I mean I would be fine making the payments, but alone I don't think I can qualify for that.

If this ends I honestly don't really want to live in the house. The house is our dream house that we finally built four years ago. If I leave she has to buy me out and split assets. If that happened I would have enough money to get myself a hour or something. She keeps bringing up 50% custody. There is no way that would happen with her traveling three to four days per week for her job/affair.

Should I just do nothing unless I am served with some sort of papers?
