Are you sureeee nothing happened? /s

The issue is all on what your best friend thinks, and honestly, no matter how you reassure them nothing happened, they are always gonna think something happened. Give it some time for the other person to come out of it or “forgive” you.

Many long relationships are ruined over simple things like this.

Basically you can do a 100 good things but doing 1 bad thing, will make you a bad guy in peoples mind.

13 year relationship can also be messed up by one bad thing.

Best thing to do is give it some time, but this is not really your fault.
