Sorry to hear of your situation Laura. Its hard to let go of someone you love, and of course it makes you sad, but after some time I hope you will become more detached and glad you made the right decision.
It's great that you have the ability to move and support yourself. Eventually he'll have no choice but to finalise things, whether he does it willingly or kicking and screaming.
All the best in moving forward. Its a pity he can't move with you, but you can't force the pace.
