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

So me and my girlfriend have been together for just over a year now. we were together for just over a month before we both went of to school but we decided to do the long distance thing.

 while at school everything was going well until the april when we broke up. after 3 days of being home for summer break we got back together. over the summer there has been a lot of arguing and fighting, as well as her telling me multiple times that she does not trust me, yet I have never done a single thing to break her trust. she's very over attached. We have a serious lack of intimacy. She seemed to get angry at me over every possible issue such as being late, and having plans to hang out with one of my guy friends (I don't have many friends at all so this is important to me). all this and more has led me to just not be into the relationship at all, of course I love her care about her, but I'm not happy.

 Finally about a week and a half ago we got into a major argument, and i told her that I don't want to do this relationship anymore and I'm just not into it. after telling her this she seemed to be in shock. She asked me for all the reasons that made me feel like that, and i told her. After all this she tells me that she'll change it all, and i decided to give her the chance to fix it. A week and a half later, she has changed and she is staying true to her word. But I still feel like I'm still not into this relationship. she has been very affectionate and caring, but every time she is i feel awful because all i can think about is how I'm not into the relationship at all, i know if i break up with her she will be devastated, but i just feel its not going to get better on my. I don't know what i should do, I feel awful and worried no matter what i do I'm going to feel like i made a mistake. what should i do?
<bot>: [19/m] is unsure if he wants to continue his year long relationship with (19/f) shes working to fix things but he is worried her changes wont change how he feels in the end.
