So you didn't hug her enough or say I love you enough. So what do you think that says about you? Are you unappreciative? Are you not gracious?
You didn't want kids. Are you worried about the responsibility? Are you worried about money? Are you worried about your paternal capacity?
It's not about solving the actual problems she cited. You can't go hug her now. You aren't going to impregnate her now. Instead, think about what she was REALLY upset about. How do you fix THAT?
