I've been with DH for 11 years...married for 2. We're 40 now and I am JUST starting to get to know him well. I can now tell when he is scared...though he doesn't show it....I see how when in times of stress or bad news he can take around 2 days for it to sink in and for him to finally react.
In the past I haven't pieced these things together or had experiences to compare them to...is this usual? HOw long have you been with your partner and how long did it take you to feel you knew him properly?
