Můj partner je extrémně promiskuitní

I've been dating my girlfriend for a while now, and let's just say, she's got a wild side. Not only does she love to party, but she also has a thing for other guys. She's always been upfront about her promiscuity, but it's starting to get out of hand. She's got a habit of hooking up with her friends, and it's not just a one-time thing. It's a regular occurrence that's becoming more frequent. I don't know what to do. On one hand, I love her adventurous spirit, but on the other, it's starting to affect our relationship. I can't help but feel jealous and insecure. I know I should trust her, but it's hard when she's constantly putting herself in compromising situations. I've tried talking to her about it, but she just brushes it off like it's no big deal. I don't know what to do anymore. I'm caught between wanting to support her freedom and wanting to protect my heart from being broken.
