Upright
Less about romance than about choosing. The Lovers usually turns up around two things that can't both be true at once, and the values that will have to decide between them. Where it does mean a relationship, it means one you entered with your eyes open.

Reversed, something is out of alignment: a choice made to keep the peace, or a connection where the two of you want different things and neither has said so yet. It's worth asking what you agreed to that you don't actually agree with.
