So, you are saying that right now you are accepting H's contact with PW and his lying about it for your own reasons. That is fine. Ellie's suggestion of putting a time limit on that is a great one, you can reassess in a month. In the meantime, quit obsessing about it and feeling like a victim. You have CHOSEN to accept that behavior in H for your own reasons, so you also need to accept the consequences of that right now.
