I romanced garrus in ME2. I want to continue the romance in ME3, however I ccidentally flirted with Spec. Taylor. I ended up inviting her to my room, but we only played chess. I read a guide that said it was too late to romance anyone else because the invite to my room locked me in, even if I didn't opt the shower. Other guides weren't as specific. Did i lock Garrus out? I already spoke to him after Palaven and in the cockpit but I'm unsure.
