Dear {Name},
I'm writing to apologize for {taking credit for project/telling on you to management/etc.} I stabbed you in the back, it was wrong, and I'm sorry.
It's no excuse, but I've been under a lot of stress lately due to {situation}. I don't know if it was my misplaced ego or insecurities that got the better of me, but believe me, I'm going to continue to give a lot of thought to what I did and make sure it doesn't happen again. Backstabbing and office politics are not how I want to get ahead in this business.
I hope we can get past this and work well together again. As a small step toward (I hope) rebuilding trust, I'd appreciate it if you'd join me at {meal/event}, my treat.
Sincerely,
{Name}
