Make plans together, without making them assumptions
A simple way to build trust is to treat plans as invitations, not obligations—and to make changes clear.
For example, imagine two friends planning to meet. One can suggest a time and place, while the other feels free to propose an alternative. If plans change, a brief update gives both people a chance to decide what works next.
The takeaway: be clear about what you can commit to, ask what works for the other person, and leave room for either of you to choose differently.
