<human>: Can you succinctly summarize the text in 1-3 sentences?

My girlfriend and I have been dating for about a year and a half.  Things were great when we started dating (we were good friends before) and we very quickly fell in love and shared those feelings.  We had a few hiccups in our relationship that were not out of the normal for any others.  However, about a month ago, my girlfriend told me that she lost her feelings for me, is no longer really attracted to me, but she still loved me.  She said that I was a really good catch and a really great guy and she doesn't want to lose me.  She said she wants to work on it and find her feelings for me again.  

I was absolutely heartbroken and to some extent still am.  She says she loves me but not nearly as much as she used to, and I always have to initiate hand holding or anything like that -- we haven't had sex since she broke out to me all of this.  I am just really sad - I still have such strong, attached feelings and she is, in a sense, restarting her relationship with me.  I miss the small things and I miss doing them with her... I just miss my old girlfriend that was madly in love with me and I want her back.

In my mind, everything was great and I was going to ask her to marry me in a year when she finished college.  She has been telling me that she is seeing everyone that we are friends with growing up and she is getting scared, so I don't know if our seriousness (relationship wise) is scaring her and making her feel trapped?

What do you guys/gals think?  I'm just really sad and I want her to be back and happy with me, and find her feelings for me again.  She is truly my entire world.
