Past relationships are just chapters in our lives. Any new relationship should be interested in what made you who you are. Good, bad, ... it doesn't matter ... it takes a combination of experiences to make up what we are today.

When the book of a person's life is offered, it should be read with interest just like any novel or operating manual. All parts are interesting and helpful.

To know someone is to love someone.

Think we all like to think we are unique individuals and will be judged on our own merits but the reality is we have a lot in common and it is not that unusual for certain words, behaviors, and patterns to be repeated so the instinctive self is alerted and a level of uneasiness is to be expected as we move forward.

Sadly some of the same things that attract the first jerk into our lives we often repeat with subsequent relationships if we don't change certain things about ourselves to some degree.

Think what probably is key is not over compensating and over reacting when someone does do something that suggest we should alert. But to try to condition yourself NOT to alert would be counter to common sense that should be applied in future relationships.

If a new person wants to over react that you are "too touchy" then I would say it is more about them wanting to get away with "too much" unless you are clearly getting input from other people who say you are hyper-vigilent or over compensating after a normal adjustment period.

It is pretty common more or less normal for people to be a little "wild" after an oppressive relationship or sad after a great loss; commonly called walking wounded. Generally passes for the most part. I would not worry about it too much. Be more afraid of not attempting to move on.
