We're not married. I was planning to propose soon.
After a few weeks of not being able to get her to change her mind and take me back I looked on her computer and discovered the OM - that was violating her trust.
Did you already know at that point that she had been the OW in a previous relationship? Sounds to me like you were just being wise, and protecting yourself considering her past track record and her suspicious current behavior.
btw, you should stick to one thread -- easier for people to follow you.
