You shouldn't have to sleep on the couch. You should be able to explain how what happened made you feel. Your partner should take the time to understand. It should be a moment where you grow even closer. You are baring your soul to each other. Understanding the inner workings.
If you are still pissed you are not communicating with you S/O... or.. they are not communicating with you.
The reality is that if you both took the time to understand each other and what happened... this could lead to an incredible session of sex that brings you closer.
I will never be with someone who can physically or emotionally detach themselves from me. If they can I am with the wrong person and I am out of there. I would rather be with someone who is secure and understands that there are miscommunications at times. Someone who realizes I love them and I did not mean to hurt them. Someone who will take the time to talk to me so I understand exactly how they feel so that I would never do what I did again. Thats love... thats a relationship!
