I don't know your background stuff except your w is having an affair and has been, for awhile.
I still feel the same about the money issue until a court resolves it. There's a reason your w has not filed or sought support. (I don't know that reason but there is one).
Does she earn a lot? If not, how is she getting by without any support?
What are your GAL?
