I think there is a 3rd option - tell your W that if she wants to continue, she'll need to find herself a new place to live. Why should you have to move out? I moved out when my H admitted his A (and wanted to continue it) but the advice on this forum tends to be don't move out.

That said - in house S whilst your W is having an A is NOT easy. Diffrent in Newcomers has done this, as has U turn and Rai.

Take care and keep posting - you're doing really well...
