Forgiveness and closeness are two separate things. Someone can genuinely accept that you are sorry, stop holding the incident against you, and still not want the friendship back at its former depth, which is not a failure to forgive but a decision about what they want now. Treating an apology as a receipt for the old intimacy puts them under a second obligation.

If you have apologised well, let the outcome be theirs. Do not press for reassurance about where things stand. And if you are the one who was hurt, you can accept the apology sincerely and still keep the distance that feels right to you.
