It has become evident lately that my boyfriend of 1.5 years is regularly calling psychics. We both divorced with DC, live separately but he stays over a lot. He says he’s using psychics as his ex wife is involved in a cult and this is his way to protect his DC for which he is fighting the access in courts. He calls psychics mostly overseas and spends hours chatting to them, from what I heard it’s more of emotional comforting but he says they predict what will happen next in his court battle 
I frankly call it BS and am pretty disappointed that an adult man, a high earner and otherwise loving and caring partner can fall for such.
According to him his DC and other people involved in the court are affected by his ex ‘dark forces’ and need to be rescued.
I also feel a bit threatened that he spends hours of what looks like emotional comfort and perhaps is emotionally attached to them (there are several, but he has the main ones too). He says I am in my bubble and I don’t understand.
I have no idea how to react. Just feeling disappointment and a bit scared of his blindness. Do I leave it be, there seems nothing much I can say to convince him otherwise...
Or anyone will come forward to say that there are dark forces and psychics can actually be of a use?
