<human>: I have been friends with this girl for about 2/3 years. She's the closest friend I have in my town since most people I know moved away.

She's sweet, fun, attractive, nice and one of the best people I know. But she also makes really terrible life choices and it's starting to affect me.

She dated a guy who is a complete jerk. they were together for about 5 years and he was a terrible piece of shit. He beat her up, gave her stitches, controlled what she did and who she hung out with, locked her out on their balcony and told her to kill herself, he even duct-taped her dogs legs and mouth out of anger. Anyways he dumped her last year and she keeps chasing after her like a lost dog. At first i got it, I was severely abused by someone too, I had been through what she had. but it's been months since they broke up and she constantly texts him, messages him asking to chill, that she doesn't care what he's said about her (he's repeatedly called her a slut to his friends and to her face since the breakup) and says he forgives him for shit even though he keeps calling her names.

She'll go over to his house and have sex if he says he's even remotely sad to her, then kick her out. This happens over and over. I've tried being supportive, I've tried helping her, I've tried getting her mind off him and giving her stuff to do but she won't leave him alone. If she didn't message him he wouldn't even talk to her at all.

It's getting to the point where I feel sick wwhen she talks about him as I was abused by someone she's close friends with and she doesn't care. Her ex is even banned from her building.

What can I even do? I'd understand if she was still with him, I've been there too and would understand if she needed time to leave and get her life on track but it's over between them and he doesn't even talk to her unless she barrages him with texts.

Give me a shortened version of the text
<bot>: My best friend is following her abusive ex who abused her and animals. She constantly makes up  excuses to try and see him even though he doesn't even talk to her unless he wants to get laid. What can I even do?
