Would you stop being friends if she flirts with your man ?

Every time I hang with my best friend and my husband is around I feel like she's always flirting. She'll frequently call him big head and try to play fight with him. Literally everytime the whole time we're together non stop all she do is call him big head and try to embarrass me in front of him like making fun of me. She will say things about my gap or call me ugly in a "joking" way... She's also asked me to have a threesome with her, my husband and I. She's a sex worker but she uses protection but her sleeping with all these different men kind of made me wonder do I really want to do this but she kept Asking. On the other hand my husband did not want to at all .. he says she disgust him also he said he never wants a threesome. But The last straw was we went out to eat with a couple of friends and at the dinner table I wanted to sit by my man of course and she wanted to sit by us she literally asked could she sit by us and my other friends noticed she was kind of flirtatious. I was so embarrassed after that I didn't do anything. After that day I stopped hanging around her. Til she text me wanting us to hang out this weekend. I said yes. While me and my husband was over her house watching a movie she had on a robe the whole time NAKED yes fucking naked and said she doesn't sleep with clothes and she wanted to take her robe off. I didn't know what to say. She didn't do it but I still feel like that should have never been said around him and she should've had on clothes. My husband wanted to leave after that so we left and she's been texting me and calling asking if everything is ok. I haven't talked to her since I left.
