Wow. This is the stuff of great books. Maybe you should write a novel... It would certainly be, well, different.
And also, this may sound crazy, but did you post at least a part of your story a while a go, because I have a massive sense of deja vu when I read this. I have a pretty good memory. Maybe I'm as crazy as you guys....
Well, if I were you, I would get out now. Just look at what you've written. You get into fights a lot, you've been on and off, she gets angry at you for the smallest things (not looking at her!?!?!) and she wants you to get a permanent tattoo. A frikin' permanent tattoo!?!?
I know that you say that you love her, but we as humans, when we look back on past events tend to put a rose tint on everything. So next time you look back don't just remember that you love her, think of all the other times, when you didn't, when she got angry at you for the slightest things, when she was disloyal, when she was mean and when she pushes your buttons.
It's your choice in the end but as your leaving Seoul so soon just keep in mind that it probably won't be long term, and if you want it to be, do you really want to have a long distance relationship with her. But if you really love her you can try and make it work if that's what you want. Not members on this thread, not her, not your friends not anyone but you.
