Your question about feeling empty when he leaves?? That kind of depends on how old/ or what experiences he has had. Me? Me, when I was younger, I used to pine as my lover left too and hunger for more... These days, I may give the impression that your Gem gives you. Why? Because I too have experienced much pain and have learnt to move on situation to situation, friend group to friend group and not worry about what is happening to the lover as it killed me in the past. Men also like to go back to their caves no matter what sign they are!
