<human>: Can you give me the gist of the text in a nutshell?

Hey guys, this is really tough for me. So in the short the relationship has been a really positive supportive one and we loved each other and were best friends. However she went and did a volunteering trip for 7 weeks which I was totally okay with.

Upon returning however, she said she has fallen out of love with me and now we are on a break. We met up today as I needed to drop some stuff around her house and we had a little talk about us. 

We had a lovely lunch date but she now says she sees me only really as a friend and does not feel like she wants to be intimate or have many feelings of love anymore. However what is confusing me is that she does not want to break things of yet because she still in love with me a bit and so we are still on a break.

This is obviously really hard on me because my feelings for her have not changed as I still love her as much as before. I just do not know what to do, should I just give her space and hope her feeling come back? Or do I stop being mucked around and just walk away for this 18 month relationship.
<bot>: She went on a long trip and came back and she is out of love with me, but we are on a break now hoping to get the love back.
