I think you need to keep in mind YOU aren't in limbo, she is. You have said several times you are moving forward with or without her: that's not limbo! Leave her twisting. Your life will keep going regardless if what she does, just keep going!
If she starts dating, then go ahead and date! (But, if she's not then don't- it's only been 2 months.) But if you aren't sure you want D, don't do anything in that regard. You want to come out of this knowing you did everything you could- that doesn't mean you sit and wait. YOU aren't in limbo.
