@Owt I’ve visited an escape room as part of a team building day within the first week of starting my new job. The larger group was split into three smaller groups of 8-10 people and each group took turns to complete the 3 different escape rooms at the venue.
Whilst I usually hate these types of forced fun activities, especially with a group of people I barely knew, I ended up really enjoying myself (possibly helped by my team winning by solving each room in the quickest time)!
As PPs have said, you can leave the room at any time. There are staff monitoring the room via CCTV at all times so you aren’t being left to your own devices and they wouldn’t pressure you to stay in the room any longer than you are comfortable with.
If you think you’d enjoy using your knowledge, logic and reasoning to follow clues and solve puzzles, you should consider giving it a try. Whilst I’m sure your partner wouldn’t hold it against you if you decided not to go, I’m sure he’d really appreciate the effort if you gave it a try.
I feel obliged to declare I studied 1 year of French, 2 years of Spanish and 5 years of German at High School and also did A level German. My favourite German word is Meerschweinschen, which means Guinea Pigs. I don’t, and never have owned, a Guinea Pig.
