My wife got pregnant with someone else's child.
Most Helpful Girl
The same thing that causes men to stray. Either she wasn't feeling emotionally or sexually secure in the relationship. This may have been something you did or didn't do, but it could also have been something she regretted since before she married you and hoped wouldn't be a problem
Whatever it was, she doesn't value your marriage and has cheated on you. She is immature and chose an unhealthy way to alleviate her problems rather than bring them to you. If you still want to be with her, then you need to talk things out. If you don't (and I don't blame you because once a cheater, always a cheater) then you need to get this mess over with as quickly as possibly and find a way to move on1
