I don't know why we're even arguing about this ..... 1) Tully has CHOSEN to hook up with Drew (and therefore cheat on her partner on national TV) (and dont give me any crap about "they havent had sex yet") because thats the only thing they havent done together yet, 2) Tahlia has CHOSEN as a result to part ways with Tully (and kudos for her for doing it in a very respectful manner, for which she should hold her head high, especially as Tully didn't show her any respect when she hooked up with Drew)
Keep in mind that Tahlia never signed up for BB!
So there's nothing to argue about ... Tully has chosen to cheat, her (ex)-gf has chosen to part ways as a result ...
ps. Drew is just as guilty as Tully though, he knows the story but is still pursuing, and that is completely disrespectful to Tully's gf.... not that she seems to care tho
