How do you deal with an emotionally unavailable woman?

I have been talking to a woman for a little over 3 weeks and we hit it off really strong, she recently pulled away and said she can't date anyone cause of her emotions.

When we talked about it she told me she likes me so much but is afraid she can't give me what i need and that wouldn't be fair to me, i told her i dont care all i need is her but she is cemented on the idea i will leave her.

How do i deal with this, she won't work at my job anymore so im afraid i would lose contact with her and end up losing her aswell.

Anyone been through something similar that can give me advice on how to ease her while also respecting her decision?
