<human>: I am 18m and she is 19f.

I have been dating this girl since we were both in high school.  She went to a college really close by so everything went well when she went off to college.  Now I am about to go to college in another state, so our relationship will end then; that is mutual.  

However, lately over the past two months we have fought a lot, and I have been contemplating whether or not I want to stay in the relationship for the summer.  It just does not seem appealing to me anymore.  When I see her it is still enjoyable, and I may even change my mind about not wanting the relationship for a day or so.  However that feeling does not seem to stay.  I am no longer eager to spend that much time with her.  I still care about her a lot, and I don't *want* to hurt her, but I do not think I feel the same as I used to.  I am unsure if I am hesitant to end it because I feel attached to her or the security  and length of the relationship.  ~2 years it a hell of a lot of time considering I'm 18.

Should I just wait out the summer and see how it goes?  Or does the fact that I have been thinking this way, posting for advice here, etc mean that I should not?  I am a very indecisive person to begin with.  That fact that we have been together for almost two years and since she has been my first true relationship makes this decision particularly difficult.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Almost 2 year relationship that has survived her going to a close college.  I am going out of state this fall.  Should I continue with the relationship through the summer if I already have second thoughts about it?
