<human>: Give me a shortened version of the text

My girlfriend and I have been in a relationship for a year. We are both 18. We have had a very good relationship. Very open and communicative. Our one year anniversary went great and I've felt closer to her than ever over the last month. Our friends call us their "favorite couple". Everything seemed great.
However, over the last week she has become very distant to me. We just spoke over the phone and she says she thinks we should break up. I asked why, and she replied that she doesn't know why she feels this way. We will be meeting up soon to talk about this in person. Should I try to save this relationship? Is it worth it? Any help would be appreciated as I am lost.
<bot>: GF [18] says her and I [18M] should break up. Been in relationship for 1 yr. Everything seemed perfect up until this last week when she started becoming distant. Is it worth trying to save the relationship?
