<human>: Give me the gist of the text in a nutshell

So, my SO and I have been together for 3 years. For those 3 years, his parents have made me feel a little bit uncomfortable, but that is due to how religious they are, so I smiled and hung out anyway.

Recently, they found out he and I were more romantically invested than they knew, so they (mostly his mother) tried to get him to break up with me by calling me all sorts of names, questioning if I am taking my career seriously, and other stuff.

I found out today that my SO's mother may have applied to jobs at my  work place and I am freaking out. I love my job, love my career, but I think if they hired her I would have to find a job elsewhere. My boss knows about my SO's mom and I, but its higher-ups that are doing the hiring. 

My company is small, only 80 people, but I would have to work directly with the mom pretty often. I e-mailed the HR person and told her about how it would make me extremely uncomfortable, but I really don't know what I can do.

I want to say most work places won't hire your SO, so it makes me hope that extends to your SO's parents.

What should I do?
<bot>: SO's mom hates me and applied to a job where I would have to work with her pretty often. I e-mailed HR, but no clue what else I can do.
