LL is a Love Language, from the Five Love Languages book by Harry Chapman, very good read. Michele recommends it.
Luv, Distance is so difficult. And she has his time more than you do, it's a tough road. The good news is that most affairs end, but I know that doesn't help your heart now. I also have PT and QT - DH is AA and QT - it's so hard not to touch when PT is your LL.
