After a year of working, I left for a higher position in a different field for another company. I gave my two week notice and the company overall understood my resignation since I wasn’t working in my desired field. Overall, I left on good terms with everyone. The company was only aware of my relationship with my co-worker a week before my resignation notice was given since it wasn't relevant until that point and we thought it would be unprofessional to bring it up out of context.
With this being a smaller company (around 10-12 people), we are all very close. The company prides itself on having company events and activities where families and significant others are encouraged to come. This makes it a bit awkward since my boyfriend currently still works for the company I resigned from. Eventually, there is going to be an event that significant others are encouraged to join (like a holiday party). Since everyone at the company knows me and knows we are in a relationship, whether or not I go to an event can give a decent amount of awkward small talk for my partner about my presence/absence.
I'm curious what my options are in handling an invitation to a company event as a significant other and if it would be considered unprofessional for my partner to bring me to those events.
