<human>: Give me the gist of the text in a nutshell

Hey guys, this is both our first relationship that has spanned over 3 months. So we're both quite young and inexperienced with relationships. 

A little back-story: Back in Dec. 2013, we almost broke up because she feels guilty of the fact that she does not like me as much as I like her. She feels guilty because she's never had a guy that cared for her so much, plan a surprise b-day party, hide little gifts, etc.  She doesn't know why she isn't liking me as much as I like her, and she thinks its unfair to me. I acknowledge this fact, and I said it doesn't matter right now, it takes time in a relationship to really like someone. We decide to continue with our relationship as though nothing has happened.

So yesterday, we hang out at my place, and I ask her what her summer plans are, and she says she wants to do some traveling. I know how much she loves traveling and I casually mention that it would be awesome if we traveled a little together too in the summer. She breaks down and starts crying. She says she does not want to travel with me and she doesn't know why. She's confused with her feelings and she brings up the same situation from Dec. 2013; its been 3 months and she still feels the same way. 

I like this girl, but I don't love her. Throughout the whole relationship we've been happy and having fun. Her family and friends like me. I hate to say this or even realize this, but she's right because this is not fair to me. I am not being appreciated for the efforts I put into this relationship.

I have 2 options:

A) This is just a bump in a relationship. I convince her to give this relationship more time. I think its too early to just give up on this relationship. It's hard to let someone who makes you happy go, but I think this option is unfair to her since I would be the only one happy and she would still be guilty. 

B) We break up. End things properly and on good terms. Perhaps, even have break up sex.
