In all honesty F, I think you are doing fine and good with the sitch as it stands. You are not allowing any cake eating, you are standing your ground, if and when needed. Why wouldn't you take advantage of any invites from the W, as long as they don't lead to cake eating. I suppose the only thing I could think you could do, would be to knock back the occasional invite. Sorry, cannot make breakfast I have to meet someone or do something, but can meet you at the school at such and such time still. Try and allow her some time to miss you, especially when she wants you. If that makes sense. Again, only you know her so personally. So you need to try and decide if it benefits the long term R prospect.
