<human>: I have been with my GF for 2.5 years and I have decided that I don't want to stay with her.

My problem is that I want to break it off as soon as possible as to not lead her on, but we have a overseas holiday planned next month that both of us have put a lot of money into, as well as moving out of our apartment. If I broke up with her now it would be incredibly hard for both of us financially as well as the awkwardness of having a month in our apartment.

Should I do it now or wait it out when it'll be less of a problem both of us?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Have decided to break up with GF, but it is incredibly bad timing, is it a dick move to wait until it'll be easier on both of us?
