Is it normal not to open up too much with a boyfriend?

I'm not making the same mistake again with my current boyfriend. We're approaching 6 months by now and these are things I haven't revealed to him:
- My father (how much his property is worth) and my earnings
- My parents' rocky marriage
- My bullying experience during my early school years or personal life
- My horrible first love experience with a future faker, chronic liar and scammer
- My current visit with the psychologist (guiding me how to distinguish future fakers with a man that gives commitment)

I've opened up too much with my past ex boyfriend, thinking we would settle down and have kids. I've invested time, energy and dedication... gave in too much for NOTHING. All that just to end up in a break-up and not progress.

Is it normal to be reluctant in providing too much information?

I've opened up too much with the liar that I had to end up blocking him in the end.
