There are a lot of unknowns here that make it difficult to give good advice
If you have already decided your marriage is over after 9 months here then this is primarily about your visa status
It does occur to me though that cultural misunderstandings may also be at work here, as its not so uncommon to talk to old friends romantic or otherwise here in the UK any more than its uncommon among Filipinos to be insecure and jealous perhaps he cant get his head round it
Is his credit debt connected to your marriage not unheard of here in any case and depending on you both marriage guidance as has been suggested might at least mean lines of communication might be opened up,which might bring about unforeseen benefits to you both
