Depression and the ambigious relationship

I've been dating this girl for a few months. Within weeks we became 100% honest with one another, she told me about the physical and sexual abuse she suffered in the recent past and how she thought she was over it when she met me, but hasn't. One day she had a breakdown and told me she couldn't handle it, we agreed to take it slow. But she was still all over me at her birthday party.

Over the weeks, she became distant, but not cold telling me she feels like she's slipping away. In public she's good but less affectionate, around me she's somber.

I find a post of her online were she states she fears she still has feelings for her abuser and it makes her feel like sh**, I never confronted her about this. I begin to let her do the approaching, she messages me telling me her biggest fear is the guy she's dating to dump her after seeing all this. I told her never to worry about that. Later chats, she then beings to tell me she's fearing that she's stringing me along. She panics when I tell her I'm meeting a female friend and wants to come along.

One day she drops all contact for a bit simply stating she can't handle ANYTHING. I get a call from her eventually saying she got put on probation at work. Her boss figured out something is wrong, and she needs to check up on it. She tells me she doesn't feel a spark but still wants to hang out with me. After that dinner I decided to clear my head from her and move on. But she calls me the next day asking if I'm mad, I tell her why I'm frustrated. She tells me normally she'd drop a guy, but for me she knows there's something more, but at this moment she needs friends now, not boyfriends.

I too begin to fall in a state of depression, barely stomaching food, not doing the things I love, and crying a lot(I've had HORRIBLE luck with women, I find one I truly loved and trusted and boom). We met up twice since then, one time she approached me feeling down asking for someone to talk to. We're not kissing anymore, but hugging. She tells me about our relationship as "I don't know". The next time was a party at her place to cheer her up. I dropped by stuff earlier in the day telling her we need to chat after the party. During the party, she was closer to me telling me I smelled nice, etc.

When we chatted she was scared this was a "we need to talk" I told her it isn't, I told her how much her love means to me, how I never felt at ease with anyone before her. She told me I've never dated emotionally available women, which she was one(she's on meds), but at this moment she can't feel anything, romance or not. We decide to the put the relationship on hold, but she fears she might not be the same post recovery, I agree to see other women, but be discreet with her unless it becomes serious.

She still chats with me almost daily. I can't stop thinking of her, and what I lost. I fear I may be friendzoned after this. I want to help her or fight for her, but I don't want to be a doormat. What can I do? How can I help her? How can I do it with the intention of not being friendzoned?
