The need to know everything

Hey ladies, hoping I can get some great advice. My insecurities from past relationships have definitely peaked since this whole COVID and not being able to work so there’s more time for my thoughts to get to me. Lately I’ve been questioning my husband about the silliest things and I feel the urge to go through his laptop, peek at his phone etc. I know it’s wrong and I need to nip these thoughts in the bud but how do I even avoid these things from happening? I don’t want to drive a great marriage, because he hasn’t cheated or done anything I’m just battling with my insecurities and need help weeding it out.
