In my playthrough of the Early Access, I had the option of Lae'zel (Medium Relationship) and not Shadowheart (Neutral Relationship). I believe I was at Medium with Gale as well so there could have been an option there, I hadn't tried. Shadowheart said she wanted to enjoy her wine and made no hint at any sort of interest in anything romantic, but I think after you make a choice you can effectively ask any other companion if they're "jealous".
Either way this likely needs a bit of fine tuning and could even possibly be a bug as Noraver said.
