Forum:Kaidan romance how to

I have a question it says in the article that: "Should Shepard choose to maintain the relationship with Kaidan, before going through the Omega 4 Relay, she will gaze at the picture before leaving" I accidentally started the romance option with Garrus, which resulted in the photograph in Shepard's quarters to now be face down, do I get an option to stick with Kaidan as a choice from here on, or it's too late? I know that you resolve the ME2 romance opotions just before entering the omega relay, but what must I do to keep Kaidan as an option now?
