Q. My girlfriend and I had been dating for about five years when I found out that she had cheated on me. Needless to say, the news came as a huge shock, but at the end of the day I decided to stick it out with her. She promises it only happened one time, and after more than half a decade together, I wasn’t ready to throw in the towel.

It’s been a few months now, and things have been pretty great. We’re communicating better than ever, and while we still have some issues to work out, I generally don’t have any major complaints about the relationship.
