break up asap

i was in a 6 year great relationship but aside form love and attraction and a great time we always knew it wouldn't work , either because of the distane we were form eachother ( aobut 2 hours) or because somehting was missing. my advise is to break it off as soon as something feels wrong rather than fall more in love which makes it harder to be freinds and to get over it in the end, not to mention the pain is much greater.
