<human>: Both twenty one year old, male and female. We'd been getting close for the past few months but this girl was always quite closed with her emotions / shut off -- I told her how I felt about her, but she could never bring herself to do the same. After a drunken night out she told me how she felt about me and she got quite upset that she couldn't put her feelings out there, said that her past boyfriend had tried to hit her and that since then she's had trust issues. I've got a feeling there may be more to it, though. 

Fast forward a few weeks and with this all in the back of my mind I asked her out, she said yes and we've been together for about two weeks now. The first week was great, exactly what I was expecting -- the whole cheesy hand holding, looking forward to seeing one another, but within the past few days she's become really quite removed -- downplaying compliments, being quite cold towards me. We had quite a frank talk last night with one another, in which she said she was having problems letting people in lately and that she knew that she'd been cold towards me and probably hadn't been the best girlfriend to me. I replied saying that I wouldn't have asked her out if I wasn't trying to make it work. It's disheartening to put in 100% effort and get 10% back; it's leading me to fear that she's purposely trying to destroy the relationship because she realizes she's not ready for one. Also, I think I may have been naive to think that by saying "yes" to asking her out that she'd accepted me in and could trust me. I've continued to remain how I am with her, like a boyfriend, even though it's hard sometimes without feeling like a try-hard, I think the last thing she needs is for me to be give her the cold shoulder back. I'm willing to make it work if she makes me feel like she is trying too.

Can you condense the text into a few key points?
<bot>: New girlfriend says she's having a hard time letting people in lately, including me because of confidence and trust issues. Whilst we should be lapping up this puppy love, I'm wondering if it's really the right thing for her.
