I've read here, and learned from personal experience, that you need to ask your partner what they want. Tell them (over and over) how much you appreciate them, and want to be with them, and ask that they tell you where the boundaries lie.
We broke those boundaries, through our affairs, and lost the right to have them. I discovered, in couples therapy, that our communication was horrible. That is what we are trying to fix. Even the mundane is discussed, to remove even the chance of tiny resentments building.
So talk to her, tell her that you need her guidance, but (I think this is what you are saying) you want to spend so so much time with her because you love her, and she is very special to you, and you get joy from being around her. Ask her to be honest when she needs space, and why, and then support her having that space. Don't mope, have something productive to do in lieu of that closeness.
And this is advice I should take, but when she is gone, do something that she would appreciate seeing done when she returns. A clean bathroom. Laundry done. Kitchen clean. Windows washed. Fresh flowers on a windowsill. That shit we never thought to do when in the fog. Show her that this person is not the same person that had the affair. Be someone that she wants to spend more time with.
Now I need to go clean that toilet.
