I agree with the advice you got here. I would add that one should try and reach a certain level of detachment, but eventually you will have to gently start pushing for some sort of clarity of what she really is wanting.
I must say I was a yo-yo DBer, and many times I would ask my H what the heck he wanted from me because I was wanting a lot more than he was giving. It usually cleared the air for us, however, eventually we both wanted the D, and soon thereafter, he declared he had changed his mind, and will commit to our M, and that he was not going anywhere ever. So far, so good, a year later.
So, just follow your gut, and do what you think is right for you, and your family. Don't be a doormat, but don't be controlling either. It is such a balancing act, but you are in the right place for venting, because we have all been where you are, and know how you are feeling. I despise being in limbo. Good luck!
