Joanna and her boyfriend Michael enjoyed

[Bassim]

I am wondering if my sentences are grammatically correct. Can I write "ex Bob" without using commas?

Joanna and her boyfriend Michael enjoyed their holiday until her ex Bob appeared in the same hotel. Their mood changed and they moved immediately to another hotel.

- You need the past continuous with "enjoy".
- Consider using "showed up at" instead of "appeared in."
- "Their mood changed" is somewhat unnatural. Consider, e.g., "they felt uncomfortable" instead.

The automatic use of commas seems to be in decline IMO. I would be tempted to use them, but wouldn't be disturbed if you didn't.

I would put the commas before and after "Bob". "Bob" is an appositive here describing "her ex". "Ex" is a noun. It is a common speech word meaning "a former husband: (or wife as the case may be).
