Hi. I read all the posts but don't really have any sage advice All we can do is to try to detach. For me it's very hard so I know what' it can be like for others. The one thing I have learnt it to STFU , I do mess up sometimes but mostly I do ok. It also helps to accept that the M is over. Maybe not forever but for now. Act as if this is the way and with time the detachment will happen. You have to let go of what W is doing or what you expect her to do. Just worry about being the best you that you can be.
