Wow man, I honestly don't even know where to start...
I have a few questions, not sure if any of this was covered in the first post cause its been deleted.
How did you meet?
How long have you been talking regularly?
Have you had any serious relationships besides her?
And most importantly, what the fuck is up with all the secrecy?!? Dude, you've been talking to her for 2 years and she says she loves you but she won't even accept your friend request on facebook?? Obviously there's something on there she doesn't want you to see, otherwise why would she care? And what reason could she possibly have for not wanting to video chat with you? I mean I get that she has trust issues, but don't you think talking face to face would be a good way to build trust?
Man, I hate to say it but in all honesty it looks to me like she's not who she says she is. I don't see any other reason for her want to hide her facebook, not want to video chat, and come up with lame excuses every time you try to arrange a visit. You say she doesn't want to see you until she's 100% sure it's not going to fail? Yeah well that's absolutely impossible, and seems to me like an indirect way of telling you that it's not going to happen. Obviously you two care about each other, no one is doubting that. The problem I (and just about everyone else) have is that she seems to have made it pretty clear that this will never turn into a real life relationship, and that's what you seem to want out of it. You also keep saying how you KNOW you can trust her and you KNOW she's being honest about everything but come on man, just think about it...do you really KNOW you can trust her, or do you just really WANT to trust her? Because in reality you can't just trust anyone and everyone, because NEWS FLASH: MOST PEOPLE AREN'T HONEST. Especially on the internet. The facebook thing and the video chat thing seem to be dead giveaways that she's not being truthful with you. I'm assuming she's sent you pictures of herself, are you sure they weren't of a friend or just some random girl? Because that probably happens more than you think.
This whole thing is eerily similar to a story I saw on TV recently...
Sex-Charged Cyber Chatroom with Posed Marine Turns to Deadly Affair - ABC News .....crazy sh*t!
In my opinion man this thing has progressed to a point that's not healthy for you or her. She's playing games with you and it's going to slowly break you down until you can't take it anymore. You seem like a good guy, and everyone's here giving you great advice because nobody wants to see you get hurt more than you already have.
Bottom line is if she wanted this to go anywhere and was truly serious, she would be more than willing to visit with you in person....and she isn't.
Sorry if that was jumbled but I had way too much going through my head to make a concise post. It was seriously sickening reading some of that cause I can't help but put myself in your shoes...
