What do I say or do at this point

I have a friend who I work with all the time, I also have her on snap. She’s the sweetest and an extremly hard worker. I admire her so much.

She is a tech at the hospital and she’s in nursing school and on her last semester. She works like 4-5 shifts a week and she’s overworking herself to the max. I feel so bad for her, but the problem is her boyfriend is cheating on her. She turns a blind eye, her boyfriend is draining her bank account. He’s constantly blowing her money on alcohol, door dash and buys random things for his gaming. He won’t keep a job, he’ll quit each one. I personally think he’s using her, but bc he is blowing her money she has to pick up more and more shifts while being in nursing school. The problem is she’s always telling me and venting and after time it’s starting to wear me out bc I clearly can see she needs to leave this guy, she deserves better he’s like killing her. She won’t listen. She found his tik tok history he liked was full of half naked woman like mainly every video was that. His whole Reddit he was searching some viral tik tokers only fans videos and he was watching all of those. He’s on so many porn sites. He found him messaging other girls through his video games. She won’t confront him bc he’s been “ nice “ lately to her so she doesn’t wanna ruin it. He won’t kiss her or have sex w her for along time now.

The problem I’m having is I can’t keep listening to it. It breaks my heart. Idk if she’s in denial or if he’s abusing her in some way to make her like this, but As much as she keeps venting she won’t do anything but allow it all to happen just to keep him. It’s getting harder for me to be there for her bc like what can I do anymore???? Do I just keep being an ear for her to vent? It just sucks knowing your friend is in a situation and there’s nothing you can do/ say to help….

What would you guys do?
