Lido,

I agree that there are different personality types. My wife travels and sometimes so do I (not as much).... when she travels sometimes I want to hear from her quite a bit, and start to feel lonely. When I travel though, I don't have the same lonely feelings cause you just get so busy and have little downtime.

It helps that we have kids now, so that provides extra incentive... and we use FaceTime on the iPhone which is really cool.

He needs to find a coffee shop and Skype you.... phones are a pain in the butt in Europe.

So in short, he probably does really care about you and think about you more than you think.
