Am I a bad friend?

My friend is a sweetheart and I love her but she’s a hardcore republican and anti mask. She never ever wears a mask and she goes EVERYWHERE. She goes to church multiple times a week where nobody wheres a mask and she even brags about it.. she posted a video of her being around people talking about having symptoms while having no mask on. She’s already had covid like 6 months ago, but you can get it twice. I’m pregnant with a toddler and I don’t want her anywhere near me. I feel bad for feeling that way and she would absolutely never understand and it would destroy our friendship but it just makes me sooo uncomfortable.
