yeah I have a thought, she wanted to have sex except you didn't close the deal and just "cuddled" so she got bored and then left, she probably would have had sex and slept over.
Don't be afraid to initiate sex, in fact you should initiate sex, if you get rejected and are told "NO", that's ok and respect her when she tells you NO, but you had your wife come home after a long day of work unexpectedly and take off all her clothes and climb into bed with you to be near you.
I suppose I should have mentioned that there was a little foreplay, but since she was very tired, she said something like "I'm just too tired".
That was a test.
WOMEN TEST MEN.
I think she wanted you to press on, and persist, and take her.
I could be wrong; at least about everything other than the bold part.
