Can our parents actions affect how we think

I have a fear of people close hiding things from me. Maybe that fear comes from dad and mother. I have always had worried about dad hiding stuff from mother. It started from when he was going to a nursing home to visit someone and would tell us he’s going to the electronic store. At that time I was around 11 years old and I thought he was cheating on my mom with a blonde girl with large breasts. Turned out that wasn’t the case but could this experience have caused me some sort of anxiety or trauma?
