Gf's love for her mother is complicationg our relation.

I have been dating this girl for almost two weeks now whose parents are separated. She lives with her mother who she loves unconditionally. And because of her father she never trusts any guy. However she fell in love with me almost six months back. And when i confessed my feelings to her that is tow weeks back, she reciprocated happily. And all was well and then we started dating two weeks back. For for first date, she didn't tell her mother because she was afraid as to how her mother will respond for her mother was extremely emotional and dramatic. Therefore she had to lie. Though she was extremely happy throughout the date, the problem started once she reached home. She started feeling bad and guilty for lying to her mother. She started assuming that she's cheating her the exact same way her father cheated her mother. And now she doesn't know what to do and so do I. She loves me and doesn't want to end things, but at the same time she says can't do anything beyond telling me that she likes me. She won't go out with me, she won't hold my hands. She wants to be friends with me like we used to be. But I don't think we can go back being friends. Its impossible now. She's killing me and herself with unwanted guilty feelings. And when i asked her to tell her mother about us, she wouldn't do that also. The worst is she loves me and she doesn't want to go beyond that. And now we decided to being friends, but this whole going back to being friends thing is definitely not working as it is working for her. This situation is basically killing me. What the hell am I supposed to do?!
