It depends.
That is why it's so important to build trust. To do that:
1. You have to be a person with integrity to begin with.
2. Loving a person means that you are actively taking steps moving towards them.
3. #1 and #2 are consistent.
These things only apply to a partner who isn't experiencing trauma or deficits in the relationship department. Someone who has attachment issues or is a narcissist is another conversation and will always come with drama.
Anyways, once you have trust then almost anything you say or do will not stir up drama or raise suspicion, and you won't feel like you have to withhold information.
Unfortunately, many people do not have the discernment to do what's appropriate and so they're creating mistrust and suspicion with their partner. And now they find themselves having to defend or explain.
