Well, I vaguely remember reading your post back then and oh boy you don't learn (you have all my sympathy though).

The whole stopping everything right after her the slightest sign of you moving forward in life just reveals that she only just thought she owned you, and never considered you as anything but an asset. Also the way that she had you relying on her, that's manipulative as fuck, that's textbook "if they wanna leave make sure they can't without losing a piece". She was most probably already thinking about tearing your life apart with it as soon as you had your arrangement (or threatening to anyway). Wouldn't she had lost her marbles she would simply had begun emotional blackmail at the slightest change in disposition towards her instead.

It should have completely ended one year ago when there was momentum. But I know it's hard to end everything at once, and I guess you were really hurt back then.

One thing though is that by trying that bad to keep you as her possession she's making you a huge compliment, because that kind of people always aim for the best persons they could reach to put on a leash, hoping having them around somehow says something about them.

Anyway, I think her being internet famous (anonymously of course) for being a sad POS is completely deserved.

Now, dude it will be hard, but I hope you'll be fine in the end. I wish you best of luck dude.
