Poor boy is probably looking for a friend, I mean God knows what he has been through -- coming from a shelter. He needs to build trust and an understanding with you. He's probably terrified and holding tight to the filly because as of right now (not having a bond with a human, being you), she is all he's got!
In my opinion, I think you should separate them and then work with him DAILY. He needs to see you as his companion, his caregiver and his leader. This will come from lots of groundwork and patience, all suggestions made here are great. He will come around.
If only horses could talk...
