i think you should reread blood promise, spirit bound, and last sacrifice and you might feel diffrently. at the end when adrian visits rose she felt very guilty and then got a little mad at his acusations b/c not all wer tru. i completely agree the cheating was bad and she should have thot a bout adrian. i think she was in the heat of the moment because she did feel bad after sleeping with dimitri.
im really glad that adrian that is in the spinoff series. he has to find his love because that would be unfair and sukkish if he didnt.
