Just to clarify, the STD tests are suppose to be on her!! The burden of proof is on her. Don't try to cushion things by offering to have yourself tested....if you are not guilty. Why would you take them, unless you've been sleeping with someone else? I've seen other H's do it, thinking it would go better with his WW. I really believe this is a step she makes in showing her willingness to work on the MR. And if she doesn't.......don't risk yourself by sleeping with her.
And, btw, this is not about you sitting home and waiting for her to make a decision as to what she wants. More than ever before, you need to be busy GAL, and not appear as if you are anticipating a call from her. And should that call come........the decision is up to you. It will all be on your terms.
So, she is back at his house while he's gone? I thought she went to her mom's.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
