<human>: Me (20 year old male) has been going out with my girlfriend (19 year old female) for about a year now. The strange thing about our relationship is that we are long distance, and met online. My friend knew her so he introduced me via online and we've been together since. 
We've been madly in love with each other for a long time and we're basically each other's best friends in a way cuz we can share anything with each other. But recently she hasn't been as loving as she once was and I just feel like in a way we're growing apart from each other as lovers and more as friends? I don't know how to explain this, but that is how it feels. 
We were planning on meeting soon (I'd fly down over to where she lives) and she told me that she also will only kiss me and that is about it for now. And that the second time I come visit, we can do more things together (but no sex. she's saving it for marraige). This kinda got to me cuz we've been together for so long, so it feels strange that she doesn't trust me enough to do things with her. 
Anyways, in a way I've been starting to realize that this relationship is amazing, but was only amazing because I was blinded by love, and I am now starting to see all the faults in her. We've been getting into a lot of arguments lately and we have a lot of disagreements on topics. But overall, we still do love each other madly. But something just doesn't feel right and am not feeling as loved as I once was. I really don't know what to do.

Can you provide a brief overview of the text?
<bot>: I love her so much, but I feel like I should break up with her, but  then again I really don't want to.
