Don't you think this is a pretty important piece of information you failed to disclose in your story.their is one important point that i have left out, no only is she lonely and bored but she has left her two own kids in the phillippines
And you wonder why she is like she is ? geeeeeeeze your new heart to heart last night is only the lull before the storm, this problem will not go away, not until probably you have managed to secure her 2 children to come into the UK, and why did you not do this in one go so that your wife has her children with her ?
You have behaved irresponsibly, you have a duty to ensure your wife has her children with her, how do you expect her to be happy when she is separated from them, no wonder
she is at her wits end, now her attitude to you is reasonable I would say, in fact quite normal in the circumstances, if you want to keep your wife, get her kids here asap, delays will only
result in your marriage most likely failing in due course.
