We were in the courtship phase.
Just because you list reasons for rejecting someone, doesn't mean you don't have dysfunctional relationship patterns. Sometimes, those reasons can be excuses in disguise to avoid intimacy. For example, I courted a woman with a tendency to avoid intimacy. We flirted, sent nudes, sexted, and told each other we liked each other. Later, she started saying things like I'm too young for her. I knew that was an excuse because if that was the case, she would've rejected me long ago. She knew about our age difference the first time we met and didn't have a problem with it. We wouldn't have flirted and sexted. She finally admitted the real reason she didn't think we weren't right for each other was because she was scared of intimacy due to childhood trauma.
I feel like you're in denial about how your parents affect your relationships and defensive about it. I posted a link to attachment theory and how it works. This has been researched and supported. Think about it. Your parents or caregivers are the first people you formed relationships with. Why wouldn't they influence your relationships the most? Why would things like your partner's music or fashion tastes be a bigger influence than your parents' relationship? What would it mean if you accepted your childhood trauma influenced your ability to attach to people?
Your choice of words also suggest you tend to avoid intimacy. Why do you have a very serious need to avoid drama? Why is your personality healthy only at times? Why not all the time? What kind of people do you relate to? Why do your partners know everything about you, but you don't know everything about them? Why do people only trust in you sometimes? You say "I don't have to share anything about me if I don't want to", why is that?
As a side note, I'll say ignoring people without any explanation is unhealthy. The only time you should do it is if you know your physical safety is in danger if you reject someone. Other than that, it's painful to the people being ignored. I understand many men get extremely upset over rejection, but you can't control how they react. You can only take responsibility for your actions.
