My Relationship/Marriage: What do I do?

Hello again Fluther, as some of you may notice, I have not been around much for the last month, since my SO got back from Taiwan.

We have been enjoying being back together after a year apart, and trying to organize our marriage, but we have hit a problem.

My girlfriend only has permission to stay here for 90 days, and about 30 of those are up. We are hitting more and more delays, and now, it looks like she may need to leave in September for 3 months, then apply for a longer visa and come back and do it all again.

The truth is, we are both very pissed off with the system right now. We have been trying to get married since 2011, with one attempt in the UK, and now two more here in Spain.

We basically don’t really know what to do. We have a nice place that we have decorated and made a home, and have started to settle in.

My girlfriend is much happier here, and enjoys the full benefit of being independent and in charge of her own decisions, and she does not want to go back, even if it is just for 3 months.

We have been looking at our finances (7,500 euros in cash + 3800 more to come by the end of September when she must return), and we are wondering what to do.

So far, we can only really see two options:

- Both go to Taiwan and get married there, then have the marriage recognized by Spain, and return, then maybe I can work there teaching English or something for a couple of years or who knows what.

- She returns to Taiwan for 3 months, gets a long stay visa, returns and we get married here. A slightly easier option, seeing as we already know what we are in for and what we need to marry in Spain, we are doing it all right, we just have started to run out of time is all.

Any ideas? any advice?

What option would you suggest?

Is there anything we have overlooked that could help?
