<human>: Ok here's a quick rundown;  
We're together two and a half years. Two months ago she moved in with me. She is 8 years older. I'm in my mid 20s.  
She came to me yesterday and looked upset. I asked her what was wrong and she said "I'm not happy". She went on to explain that she wasn't happy with us, nor with the house we live in, and that she felt that she didn't have the love for me that she should, and doesn't know if she ever did. This came as a huge shock. We talked for a couple of hours, hugged and kissed and shed some tears, she said felt glad to get it off her chest and had been feeling like this for some weeks.  
I don't know what to think. I love her with all my heart, and I truly believe she did love me, and has the capacity within her to love me again.  
Its like I don't believe her when she tells me she doesnt know if she ever felt the love. Shes called me the love of her life, the man of her dreams, her soulmate... all that. And now she doesnt know if she ever did?! I feel so sick. Hurt.  
Some quick back story; When we first started dating she was 2 years out of an 8 year relationship. She didn't want that relationship to end, it wasn't her choice. It took her a long time to get over it and deep down now I think she never did. She says that maybe she has had a block on her heart and has huge fear of letting me in. Truly in.  
Shes staying in her sister's for a few days, we decided it was best for her to get some head space. We're still together but I don't know what I can do.... What I should do... I'm numb.  

I don't know how well I've explained the situation. I haven't slept and I'm not exactly firing on all cylinders.

Can you condense the text into a few key points?
<bot>: Girlfriend told me she's not sure if she ever truly loved me. I don't know if i buy it. She's staying in her sister's for the next few days to gather her thoughts.
