Marriage survives affairs of all types, during hard times sometimes we stray. I have no doubts there will be a day when you find yourself with a friend that suddenly becomes a lot closer to you than you even realized was happening. You have to take measures to prevent it from happening in the first place and more drastic steps once you see signs of love.
You don't have to completely shut an EF out of your life, but you have to change things so you spend less time 'with' them, confess all the secrets and you have to stop sharing things with them they you don't share with your spouse.
