Okay, say you screwed up and some chick LJBF'd you, but still you think to yourself "if I don't find someone I like better, I'd like to give it another go with this one." It's a common strategy to cut off contact with her for a while so those friend-feelings she has for you die off. How long should you wait? Is 4 months good? How likely is this strategy to get you a clean start when you try her again? I'm not asking how likely it will be that you'll bag her next time, but how likely it will be that the friends issue won't be in your way.
