I wouldn’t go so far as to say someone can’t worry about stuff like this. Emotions like worry can happen as a result of prior trauma, generalized anxiety disorder, and several illnesses that have paranoia in their symptom profile. It’s fine to have worries and that manage your worries in a healthy manner, such as therapy, medication when appropriate, meditation, and speaking transparently to your partner to try and figure out what is triggering your worry response (rubber ducking your own brain!).

It’s important to separate emotion from action. You can experience an anxiety inducing thought (such as my partner might be cheating on me) and behave in a variety of healthy and unhealthy ways.
