Is there a right way to romantically connect with others?

Hmm, interesting. Logically speaking they're both equally to blame, yes. But we do live in a monogamous style society, on the whole. So you could argue that it's the person who deviates from that who needs to speak up.

I wouldn't say they've done something unethical, they've not tried to trick the other person. They genuinely thought it went without saying.
