It doesnt matter. Its better than goin into the wedding with anger, guilt and depression.
so wot will cancelling the wedding do for you? will it wipe away the rape?
Of course it wont, but the fact is that rape is always followed by some sort of psychological trauma. The lady might have this guilt or uncertainty within her 'does he still love me, does he blame me?' and several depressing questions like that. The guy on the other hand might also have his own worries 'did she cause it, did she enjoy it, was it my fault?' etc. Some people might not be able to cope with such stress, and they might end up having an unhappy marriage cos things might never be the same cos anytime the guy is angry, she might start thinking its cos of the incidence. Let them postpone the wedding, go for psych evaluation and counselling, redicover each other before they take that bold step into marriage.
