Sometimes. It's best to admit everything changed. Than to pretend nothing happened.
Thats the first step to reconciliation.
That's where all the parties involved in situations admit each faults and let each other know what they felt. To clarify, to understand and to reason out. Unless the other parties mean nothing to you, in friendship or relationship. All parties have to put in a creditable amount of effort to get everything back to the right track. Certainly, it will not be like the last time, but it will certainly be on the right track.
Falling back and thinking the whole world hates you or the whole world is in the wrong doesn't help. It is selfish and self-centered. Cause the point isn't about you or yourself. It's about everybody.
No use pretending nothing happened when you and everybody know something happened.
If friendship/relationship means something to you.
Do something.
