Long distance relationship problems (ASD with a Bipolar)

Please forgive my ignorance on the subject of bipolar, relationships, I'm only familiar with basic ideas. 
Not really too sure how much background info I should give, but here it goes.

I started talking to my ex (I will call her K) a little while ago. She has bipolar disorder, and is on medications for it, I have Asperger's syndrome, I've also not met her in real life. We had dated for three months last summer. I had trust issues, she had communication problems, I wasn't sure what was going on after a week of not talking, (apparently the fault of our cellphone carriers not getting messages through, common with things going across the border to the US from Canada and vice versa). 
There was suspicious signs of other things too, like how it seemed like I wasn't allowed to see her complete facebook profile (she listed us as together so I guess that's all that mattered in that case).

Then there was this meetme app that looked like she was using it for dating ( I only know because it came up on my wall), she was using that but not talking to me. After I was in the hospital for trying to kill myself.

The other problem was with third parties getting in the way, another lady who was almost with me (and ultimately didn't get to have me because she not only couldn't decide what she wanted and had been leading me around for months) went behind my back and told this K now off (the night I tried to kill myself for the second time). 

We didn't talk to each other now for four months or so, and even though she had tried to be with other people it didn't work out. Our mutual friends, when I had talked to them said that K was mostly pretty miserable without me, and when we finally started talking again. There were other signs that had pointed to that, she was quite literally crazy about me. 

So here's the problem I have right now with this. I really care about her. We had been talking a lot more, but I'd told her that if we were going to be together again we needed to do it slow. 
I feel emotionally guarded right now because I had felt such intense emotions in the past six months since we broke up, about leaving K, being lead around more by that other woman, my future (there's drug addicts living at my house because my father let them in. Having seen what the one addict had done to my father, knowing about the things he stole and the lies he's told, it hasn't helped my ability to trust people), not really fitting in anywhere, and the same thing happening in this relationship. 

I want to trust her, but I don't know how I'm going to if we're not talking at least a little more, she's been playing games so much now we hardly say a word to each other. I don't know if I can do this, but I don't want to hurt her like I did before because I really care about her.

Maybe this is just a recipe for disaster, I really don't know. It's late, I'm having a hard time thinking. Can this even work, given our disorders? 

Hey LostMan,

From what I read it seems you are both very guarded, for good reason, but still, if neither of you are ready to let your guard down, waiting for the other...

So question - if you open up, what's your gut sense? Would she be open to it, or is it more likely she'd berate you for opening up?

She's berated me before when I was trying to tell her the same thing when we were first talking again, and I caved in because I could see how that it had hurt her, she said that she had the same things going on, specifically she was worried that I'd just be gone and never come back. But now that I'm here she's been gone for a week.

The problem is that right now I have too many trust issues for a relationship, let alone a long distance one. And I'm perfectly willing to acknowledge that it's mostly, if not all my fault at this point. I'm just trying to think of a way to tell her without getting her hurt, I want to be a part of her life still, but I just can't be that part because of who I am.

I think she should try to see other people (she's bisexual) who could be a better help to her right now in her life, I'm worried that when we finally see each other that it will turn out we're not really all that compatible.

From what I see, I think you are right. We're both guarding ourselves so we don't get hurt, and more than likely worried about different things. I guess there's no real way to get around the hurt with this one is there?

I'm writing a note right now, I feel so wrong in this relationship, but at the same time I feel so wrong taking a step back.

Xdude, you were correct.

I managed to talk to her a little bit today, we're both still kind of scared of each other, which is why she had been escaping in the Sims right now.

Even though we're both unsure, being with her last year made me really happy, so I'm willing to try it again.
