Hello,
Thank you for reaching out to us.
Anyone in your shoes will be confused as to how to feel as well. But, it’s okay to accept that you are hurt.
You have only one option though, which is to ask your friend about it. Communication is the key to resolving any issue.
However, there are things to consider before you do:
1. Ask your colleague if it’s okay you mention it to your friend because you don’t want it causing an issue between them. Give them time to talk about it first.
2. Ask your friend nicely, not as though you are entitled to her life’s decisions, as though you are concerned as to why she didn’t tell you as her best friend.
3. Understand that she doesn’t have to be sorry, listen to her reason and walk through it together with her.
4. Don’t lose your friendship over this, except of course she doesn’t want it again.
We wish you all the best.
