You see Eduardo, the situation is complex and more details are needed to give you some good advice. It would be necessary to know if she really forgave you, if it was you who forgave her, what happened and how to leave that as forgotten as possible. This sometimes only does the weather.
Once this has been solved, you have to know if he has you as a simple friend or if he is considering something else and what he currently thinks of you.
Once you know the situation and the cards you play with, you can move forward with greater certainty.
To give you an example:
If it’s been a long time that happened, great, you don’t need to distance yourself or anything like that.
If what happened was nonsense, then great, as if nothing else happened.
If he doesn’t have you in the zone of just great friend, one less thing to fix.
In this case, it would be necessary to surprise her with some facet of you that she does not know and may love.
From there, move forward little by little, without making a mistake.
It is very long to explain but I hope I have helped you a little.
All the best.
