i've always wondered why people in relationships cheat, and when they do cheat try to have a legitmate excuse as to why they did it. Like they'll be in the relationship but as soon as something happens that they're not cool or comfortable with, they go outside of the relationship & deal with someone else, like the excuse they use will some how change the fact or make it a little less bearable. At the end of the day if your're not comfortable then you can 1) let the other person know that your unhappy or 2) if it's that bad you can leave the situation all together, cheating to me is never justifiable. I do believe in 2nd chances but something like that to me is just not something you can just brush off or kick under the rug.
