From the OP first post......
'"Could I get a temporary (tourism or other) extension (at Jomtien) after my marriage extension expires, then meanwhile put the money in my bank for 2 months before applying for the 1 year extension again?"....
Seems he implying possiblity of obtaining funds if can buy some time.
Hence my suggestion of exit.
Still not clear if he used his 60 day extension to visit wife on this latest entry.
So that's also an option.
