Hello hello1610: Welcome to PsychCentral. I'm afraid I can't answer your question specifically. From what you wrote, it sounds as though a cooling off period would be appropriate; at least until after your exams are completed. I didn't get the impression, from reading your post, that having this relationship end would be the worst thing in the world from your perspective. It doesn't sound as though you would be devastated. So, assuming this is the case, & given the lack of trust this incident has fostered, maybe if such a cooling off period results in the end of the relationship, then perhaps it's for the best.

Of course, only you know how committed you & your bf are to this relationship. If the two of you do wish to see your relationship last, then perhaps some couples counseling would be in order. Suspicion & dishonesty do not provide the most stable foundation upon which to build a long-term relationship. I wish you all the best...
