I would be if he did at one point and now doesn't. And I don't know if I would call it mad, more hurt or disappointed. But if he didn't before I would expect it to be the same. I can't be mad if I knew it going in.
No I wouldn't be mad. I mean, maybe if he has in the past but suddenly stops, that would be upsetting, but maybe he just isn't comfortable with it and needs PDA to be private. You should talk to him about it.
