What do i do about my relationship?

If you hang out with her and do stuff with her then the temptation will always be there even if you dont leave your girl and you dont want to regret anything and ruin your freindship with her so i think you shouldnt talk to her and stay with what things are dont be a sneak and go behind peoples backs if things do end up working out in the future let if work on its own dont force it cuz wuts meant to be is meant to be and things happen for a reson so remain friends with this chick and if you really start diggin her again then you commit to that one girl you love. I once went threw this situation and i eneded up with the one i was cheating on my b,f with for almost a year! but it was ment to be and i couldnt be anymore happy.
