Yes I can see where Pinn is coming from. Scrant, you see the watching of these shows by her as a link to your past together. Perhaps she does feel some fondness and that the memories are happy. However, I also think that by being her 'supplier' you help to keep her in that place of comfort - where she can watch the shows supplied by you and feel a link to you - some reassurance that you are there for her should she need you (or change her mind.)
However, there is also merit in minimising contact and not kindly doing stuff for her. That leaves her very much alone with OM - and of course he is a bit of a moron. It would probably give things a bit of a shake up if you did start socialising with some singles - even if just on a friendship basis. Better that than being 'reliable' and kindly supplying stuff when she asks for it. Being a little more unpredictable is no bad thing.
Though I do understand where you are coming from. And I recognise there is a lot you don't respond to, and I also think you manage your emotions well when you are in contact with your W. I guess I'm just providing another perspective and of course you'll decide what feels right to you.
