You could get married. Get another job. There's some options with volunteer/ED visas. In some of these cases, consulting with a visa agency could be a good idea. The only one I have personal experience with is called "Star Visa". But I'm not sure if they do anything other than Thai Elite.
And, of course, as said in the other forum, you can get a 30 day extension with an embassy letter. Which could possibly be repeated (new embassy letter each time.)
You could to a nearby province (making sure the hotel registers you properly.) I saw someone post the other day. I think it was Ayutthaya. Immigration office was quiet and friendly.
