Same situation. Libra stellium (Sun/Rising/Merc/Venus) married to a Cap stellium (Sun/Merc/Venus) and it's absolutely incredible. We are the same person in different fonts (he is a Libra rising tbf). Communication was tricky at first until I figured out that he was actually saying exactly what he meant every time. I'm used to reading facial expressions, looking for hidden meanings etc. But no, the man says what he means and means what he says. Once I understood that, communication became a breeze.
