It depends how long you've been outside of the country for each of those years. If you've been in the country for at least 183 days for each of the preceding 5 years, you should be able to get an APRC. You also need to have earned a certain level of income, though.
I would apply for an APRC anyway, regardless of how long you've been in the country for each year. The worse that can happen is that they say no. But if they do decide to grant it, then you're home free.
If your application gets rejected this time around, do as others have suggested and unofficially separate from your wife and apply again in another two and a half years' time. Make sure your wife does not have access to your name seal.
Your college degree from back home is not 'useless'. If worse comes to worse, you could come back to Taiwan as an English teacher, you have a degree and a UK passport, so you will have no problem getting an English teaching job. At least this way you will have a steady source of income, and possibly an apartment and Mandarin lessons included. You could be looking for a more permanent film job in Taiwan while maintaining a safety net of being an English teacher.
I think even if you get divorced, these past two and a half years you've been in Taiwan for will count towards the 5 year requirement for the APRC as long as you don't leave for more than 183 days, easily achievable if you decide to be an English teacher.
