So sorry to know about your situation...
I doubt he will leave the Philippines even if you will give him a plane ticket back to UK, because he basically a:
PENSIONER (living comfortably with your money)
DEPENDENT (shelter, food, clothing, vices and all)
He may receive odd amounts of money from his employer (?) - what's his work? But, yes, they are all right - better find a good lawyer and file an annulment.
Did you make a Prenuptial agreement? If not, he may have 50% of all your properties as they are CONJUGAL... (hope not)
