Not at all!

We can’t know everything about our partner in the first year, and while we will start to get to know our partners so we’ll over time - we will always have more to learn about each other. You never stop learning about your loved ones.

It’s also human to forget some things.

My friend forgot that her own mother is a Vegetarian and has been for a very very very long time. Her mom laughed about it.

Your girlfriend is being very insecure, and is blaming you for this when it’s something only she has control over and can change.

You sound caring and are doing a great job trying to help her feel special. She is not able to handle a simple mistake and could use some therapy or more experience in relationships.

I’m sorry this has happened. It sounds like she isn’t mature enough yet, and it’s not your fault.
