Hey, Thir. As with many things, I guess yes and no. A big question is, why was the trust violated. In my experience, a lot of times when people lie to you it's because they are in some way afraid of your response. I would hope my partner would feel safe telling me the truth, even if it would be distressing to me, and know that I would have feelings about it but that I wouldn't punish him for it. So I think that if trust is broken in sort of ordinary, day-to-day things, it could be regained if both people learned from the experience and were able to alter their relationship dynamic.
I don't really believe that there are trivial violations of trust, but obviously there are more or less serious ones. With something serious, sadly, I'm not sure trust could ever be fully regained. It doesn't mean that I would necessarily end the relationship, but I do think that I would be more wary, more careful, about whatever that issue was. It fits in with what I was saying before, that I trust completely until there's some new information that indicates that's not really reasonable. A major breach of trust is, in fact, information of just that kind. I think you can accept it, and work it into your relationship, but I don't think that information will just go away.
