<human>: Elaboration on title: I am planning to break up with my girlfriend of 5 months, probably the next time we are alone; the reason for this being that I feel no proper connection with her and I don't find her particularly attractive anymore.

  I am fairly sure that another girl is interested in me, but I can't say so with 100% assurance. I am fairly attracted to this girl, I think that there could potentially be a relationship between us in the future, but another guy I know is into her and I am really at a loss for actions here. I don't know if being passive after breaking up with my girlfriend is the moral thing to do, and I am not sure how long after my break-up is long enough to respectfully move on ( I am fairly sure there will be no emotional hang-ups for me.)

  Any and all advice is welcome on how to proceed, and how to break up with my girlfriend sensitively.

Can you summarize the given text in a few sentences?
<bot>: How do I break up with my girlfriend? How soon is too soon to move on? Am I being a total ignoramus/arsehole?
