I think Jack is - genuinely - rubbish at deciding things for other people. He offers, and lets them know what's available, then stands back and waits. Especially romantically/sexually. He's a pathological flirt, but he's not one to make the decisive move.
...I'm not sure about admiration, though. Perhaps envy. If Jack did everything in his power to do something, or maybe change something, he'd be capable of terrible destruction. Jack has to draw a line somewhere, and say what he will do and what he won't. Ianto didn't show that kind of restraint because his powers were totally and completely human, and very innocent in his belief of what Lisa was. Jack can't do that.
