There's nothing wrong with emotions. They are what make us human, after all!
Just try not to base your DECISION-MAKING on them . . . especially your IMPORTANT decisions. I bawled like a baby many times during my wife's affair, burying my head in a bath towel in the bathroom at 2am so my wife and kids wouldn't hear me. But I'd like to think that I made my decisions based on my plan, and not on those emotions which swung wildly all over the map.
Cadet likes to tell people here that they've been given a gift -- a gift of TIME. Use it wisely, to figure out who you are, what you stand for, and what your core beliefs are. You will make yourself a better person, and simultaneously have the added bonus of being more attractive to your wayward spouse.
