My Husband Had An Affair And Got Genital Herpes. I

my husband had an affair and got genital herpes. I am very scared and worried about getting this. I have read about it and am still very worried about it. If he is having an outbreak on his penis can he kiss me or will his saliva cause me to get this. I have read that using a latex condom and also taking daily medication can help prevent it. But he has told me that taking the medication daily prevents your immune system from fighting the outbreaks and lowers your immune system.
