Brosef.
So. I've got a 'girlfriend' who lives across the country, literately. I've never seen her face, I've never heard her voice, and all I know is her name and AIM account. This has been our relationship for the past year. She's super touchy about going anywhere past where we currently are due to past guy problems.
Sometimes, being a friend is all you can be. Even when you give your all to her, she may still be 'blind' to your generosity, and go for some other douchebag. Voice your opinion (don't force it, voice it), and stand by her. Once he dumps her, you'll still be here. Eventually, she'll get the picture. And even if she doesn't, you'll still be her best friend, which is what she /really/ needs.
Sure, it's frustrating, even kind of heart breaking to see the one you care so much about go the way she obviously shouldn't, but there's only so much one can do about it.
I guess you probably already knew all of this. By the sounds of it, my entire post has been moot. But I wanted to comment here for a few reasons.
1. You're a boss, and I couldn't read this thread because your massive guts were in the way.
2. You sound like a guy who knows how to properly treat a woman. Reproduce, and Humanity can be restored.
Good luck to you sir. You're not alone.
