My wife is a very girly girly woman, so she might be waiting for me to make a move, she knows how I feel, but maybe wants to see it, but when I'm around her I act very cool, polite, friendly She keeps coming back, so I'm not pushing her away at least!!
But, she doesn't come round when we are alone, the kids are always there, if she comes round when there is only me home, that might be the time??
