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".
A couple days earlier, she met me at work to get her car looked at (I am Sales Manager at a dealership) and then went with me to pick out new glasses. We went for lunch after and while we were there, she said something like "I bought me...well us...something" "Do you want to know what it is"? I said no, I will wait until you invite me over to find out.
Obviously she was referring to some kind of sex toy or something, and I was of course interested - but I felt like playing the game.
