I have been dating a girl "officially" for 6 months now. I am an RM and she is not endowed. When we first started dating, that new physical attraction was passionate. There were two instances (literally only a few days apart) where we were involved in some heavy petting at the beginning of our courtship.
It was literally only a few minutes after the last time it happened that we realized what we were doing. We don't know how it happened, but the temptation got the best of us. We talked that very same night and promised ourselves we wouldn't let it happen anymore and have gone to the temple (for baptisms) almost weekly ever since.
Now we got engaged last week. We met with our bishop to discuss the process before to prepare for the sealing. He asked us a couple questions to make sure we were clean and worthy. He asked us directly if there was any petting going on. I answered that we were worthy and there was not petting going on, because in my mind these things were six months ago and we haven't done anything wrong since then. They never became a pattern. This is also why we continued our temple attendance. The more I think about it though, it is now beginning to weigh on me when it hadn't before. I've felt like we were taking correct repentance steps by discontinuing the behavior, confessing to the Lord, etc. but now the more I think about it, the more it begins to weigh on me.
My question is, should I confess this? You would think an RM should know this, but I'm just wondering if we need to confess it if it was 6 months ago and we've been clean ever since. What advice do any of you have for me? If this alters our wedding date then that would be hard to take, and would also make our past transgressions pretty much public (since everyone would wonder why we changed our wedding date, etc.), but I also know that those things are nowhere near as important as making things right with God.
I should also mention that this isn't only my decision, she and I are in the same ward and talked and decided that we'll both go into the bishop together if we end up deciding it to be necessary.
