Because the home was empty and W wasn't usually going anywhere. In the past, I had tried to initiate sex. No undue pressure. Just an attempt to initiate that then lead to an R talk in the past.
This is pressure. Whether you intended to initiate intimacy or not this time is not important. You have done it in the past and it is what she was expecting you to do that day.
Look at it from her side ...
1. She expects you to initiate intimacy 2. She does not want to be intimate 3. In the past when she has rejected your advances it has led to R talks 4. She does not want to have an R talk. 3. She does not want to hurt your feelings so she gives you a non committal response
You call her on it, it leads to her being defensive, and "ridiculing" you, and finally admitting that she did not want to have sex with you. You then tell her you don't want to go "Because I said so".
Where exactly in this interaction did you score a win?
