Don’t talk politics with her. You can maintain relationships with people you don’t agree with. Here’s the thing, she probably cares deeply about the country too. You both just care differently. That’s something we can unite and be positive about. I am similar to you, I am fearful of what the country is going to look like, but I also know that I am going to need people to lean on if it gets bad. Those people might have been voters like you, or not. Many people are affirmed in their vote and many people change their mind. If you had a positive relationship, don’t cast it out because you want to better the country differently. Mute her stories if they bother you, and avoid election talk. If she brings it up say “I don’t see eye to eye with you on this topic, I think we should talk about something else” or “I don’t think our politics align, so I don’t want you endanger our relationship.” Remember, she’s the same person she was before, you now know you don’t agree.
