I cheated on my fiance

I slept with my sons father (my ex boyfriend). I'm getting married in december.... I love my fiance with all my heart. Some may say "no you don't because if you did you wouldn't cheat". Well the fact is I have about three years of history with my ex, plus a baby. My fiance is away at boot camp so being alone for the last six weeks made it more difficult to fight him off. Is it justified... no... but I can't shake all this off. I know I will never do it again. My judgements were very wrong. I am not the cheating type. However my fiance has a zero tolerance policy for betrayal. I don't want to lose the man I love. What do I do?

Hi there. Honesty is the best policy but in this case some things are rather best kept secret because if you tell him, there are 80% chances that he will end the relationship. Don't say anything because if you do that would be your BIG mistake. Please don't cheat again
