I doubt your ex will come back to the UK Mick, why would she spend £500+ on an air ticket and risk being deported straight back to the phils from the UK. Even if she did get back to the UK, once her visa expired, that's if its not curtailed first be the H/O she would have to leave the UK as she would need your help to apply for ILR, or she would become an over stayer and sooner or later she will probably be caught and be deported.
just report that your marriage is over to the H/O and that's all you can do, and forget about it and her, and move on leaving this sad part of your life behind you
