I am afraid that I think that what you did is not right and you know that. And, when we make mistakes in life, we need to confront them or there is no rest in our conscience and we get nowhere (except more issues that develop from it).

I think it is essential to confront the situation and talk to your sig other. These feelings you are having need to be discussed with them. Living life like that (checking up on others and lack of trust) is not a rewarding way to live.

Be strong...and talk things out.
