In an LTR with a chick I met in college in my college town, 7 months now. We moved back to the city because of the pandemic. College is online now but she doesn't want to keep living with her parents. Some of her friends are moving back to my college town which is a 1.5h drive away and rent is cheaper there, so she is considering moving back to the college town. I already know I will break up with her if she does, I like her but have no issue going back to spinning plates.

My question is, should I tell her I will break up with her if she makes this choice or just keep quiet? Not really sure how I go about it.
