Another player romanced a character, does that lock me out?

Hello, I'm in act 3 now and never got any romance options with Karlach and Lae'zel. I just now realized, a friend that played act 1 with me had started a romance with both Karlach and Laezel before. I took his character out of Withers' wardrobe and talked to Karlach and Laezel, and they both said something along the lines of "I thought we had something, no hard feelings." My question is, am I forever locked out of romancing them now because he already romanced them in the past? atm I still don't have any option to romance them. Thanks in advance for any info!
