Gee, I hate to see things like this happen.

Tom, if you cheated once and got caught and she agreed to take you back, it's gonna be a long, long, long time before she's going to be able to trust you again. In the meantime there's going to be lots of suspicion and doubt on her end. That's something that you're gonna have to put up with until you can regain her trust.

tommie, if you care for him and want him back, but fear you can't trust him ever again, then why bother continuing on in this relationship? If you decide to try again, then there's gonna be times when you're just going to have to bite your tongue and suck it up, or your lack of trust will eventually drive him away.

Whatever the two of you decide, I wish you the best.
