Update: we had another date. It was kind of a beach date so we for really close, physically. We held hands, touched each other's skin. We also talked about fears and boundaries. We talked about sex. We got emotional.
We know we're living something special, and I think that the key is that both of us have partners and have a very open and calm approach to this. There is no rush, there are no expectations, no intent of being the one but being friends, close friends, that kiss and may end up in bed. That kind of friends.
