You're not cold, Laura. Look at what you did for Denny. You feel things deeply, which is the opposite of robotic. You just keep people at a distance. My husband used to be like that. He pushed everyone away by being a sarcastic jerk because he was afraid of getting hurt. But when you find the right person and you work at it, you can bring those walls down. Alex did. I know you can too. Maybe your ex just wasn't the right person for you.
Give it time. Things aren't going to be perfect right from the start. I know plenty of people who were raised "normally" who have found themselves in this same situation.
