<human>: Can you give me the gist of the text in a nutshell?

My gf and i have been together for just over 13 months and before we were together we were best friends. At first the relationship used to be great and i thought i might love this girl but later on around 7 months into the relationship we started fighting every once in a while over silly things. Gradually the fights got worse and we would be at each others throats for 3 days per fight and then things would go back to normal. Reddit I think i have finally had enough of it and want to break up with her gently. The only problem is she is my first official girlfriend and i don't know how to do it and still give her the impression and image that we can still be friends after it (i've never broken up with a girl before). Please help
