Congrats for finding A!
From my perspective, you have more of a V than a triad. Being in a triad, there is love between all three members. Like in our situation Sunshinegrl & Aussiebloke are married, SG and I love each other and AB and I love each other. If I were in love with one and not the other, even if I occasionally 'played' with the other, I would consider it a V. Not sure if you were really asking, but the title implied lol. So there's my imput. That and the fact she wants to find her own husband. Perhaps it might migrate into a quad at that point, but it doesn't seem she's truely interested in a triad.
