Thanks NYCindie and yes in a perfect world that is how it would be but the reality is a little different. He's feeling "flat", probably because he knows he won't see her again for some time. He has quite a bit on his plate at the moment (normal real life stuff), that he could forget about while she was here. And he did put a huge amount of energy into their time together.
Love might not be diminished by more than one relationship but energy can be and energy is the part of love that we actually feel. He hasn't got any energy left to be his normal self let alone any extra to make me feel special. That's why I think I'm feeling so anti.
