Liron - the Gerushah also becomes a Chalalah (Beraisa in Kidushin 77a). However, you are correct in pointing out that when Rashi explains "Mah ha'Mechalel," he only mentions that the Kohen makes his children Chalalim by living with a Gerushah, not his wife (as we wrote). We stand corrected.

The question remains, why didn't Rashi mention that the Kohen also makes the Gerushah into a Chalalah, as you pointed out? The Meiri, in fact, mentions that both the children and the wife become Chalalim. I have not yet found anyone who pointed out this discrepancy.

Perhaps it would not be correct to say that the Kohen makes his wife into a Chalalah, since she is a willing partner in the act and thus she is making herself into a Chalalah. The truth is, though, that even if he rapes a Gerushah he makes her into a Chalalah, so this answer is not completely satisfactory.

Perhaps Rashi is alluding to the Drasha from which we learn that the Kohen cannot become a Chalal from a Bi'ah Pesulah. We learn it from " Zar'o Mischalel v'Hu Eino Mischalel" (Sotah 23b), where the mention of the Chilul of his Zera in the verse is a pivotal point.

Thank you for the ,
