The tension seems a bit thick between you and SW, hopefully it will smooth out in the near future.
Not to doubt her version of things, but that line about doing the HW'ing only for you, is a crock.
She visited him twice, slept with him, fucked him all night, all of this outside of your presence.
Now it turns out she did it all for you? I don't think so.
Maybe a time-out would help defuse the tension. My belief is that once she understands she can have sexual freedom to see other guys, her libido will return.
