Alright dude...here's my take. As long as the two of you are apart this will never work. You seem to have major trust issues with her as well (which seem to be well founded) which may also make it difficult to patch things up even if you weren't seperated. From experience I can honestly say that the bitterness you're feeling now will continue to haunt you should you actively pursue a way to work it out. It will make it hard to trust her and without trust you've got a shitty foundation for a relationship. Factor in her "substance" problem...whatever "substance" that is...and you've got an even MORE volatile mixture. It's hard to say how this one will turn out. She's your "highschool sweetheart" so to speak so it's not like it's the easiest thing to cut your losses and say fuck it. Then again given everything you wrote it sounds like you've already made up your mind in a sense. I'd let her cool off...maybe a few weeks or even a month. If she doesn't call you then maybe give her a non chalant call and see what's been going on. If she did, in fact, nail the above mentioned guy then cut it loose. If not, you can begin to consider whether or not this relationship is worth salvaging or if doing so is even possible.
