With my ExW it's one of 2 things. Either she is pulling me in or fulfilling her fantasy that her and I will still be friends. Neither of which I really want. To answer the talk question the chats are 95% only kids and scheduling. The odd time there is some baseball chat. Never any R talk only D talk of it strays from the above and D talk is only over the phone. Never in person.
It has started to feel like I have no one left really to talk to that won't roll their eyes. And unless they have been through it they don't understand
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
