@Aly ****
you are both flying into Thailand, so until you are together in a little over a month after you get here, you both have not crossed a land border into Thailand. You are allowed two land border crossings a year, but there is no limit on the number of times you can fly in. My suggestion only involves one land border crossing for each of you, and then a second one if you so desire, taking each of you to four months, with extensions. If you want more than that, just fly in and out. Myanmar is great to visit now.
