Does anyone else have this attachment style, how are you working to make it more secure ?

I never feel like I can share my true feelings with any of the guys I date, I’m very private about my thoughts. I often feel like I don’t have feelings for any of them, I’m so detached and used to being a lone wolf. The thought of being emotionally open with a man disgusts me. I only open up to my best friend, my mom and some close female friends. A lot of men say I’m reserved and quiet, they can’t tell how I feel. They all say they can tell I’m very comfortable with myself and I’m good on my own though. I just wonder if this is why I’ve never been in a relationship.
