Desperate need of advice

I have a friend who has had what i would call a "perfect" relationship for 6 years with a guy who never once cheated on her and never betrayed her in any way and was always there by her side every time she needed him, she even left him two times to live with her friend she worked with last year which led to her roomates boyfriend assaulting her three times within the 5 months her and her friend lived together. And no matter what people told her she refused to go to the police and refused to go to the hospital. On the third time she was assaulted she showed up at her fiancés house with no shoes, no phone, and without her wallet after being assaulted by her friends boy friend for the third time and ripped her out of the car and stranded her 8 miles away from her apartment. She walked at least 6 miles to her fiancés house and got there at around 6 am after walking shoeless for 4 hours. She refused to call the police and refused to go to the hospital again for the third time and because her best-friend was accidentally hit while my friend was defending herself from her roommates boyfriend was arrested and charged with assault. During this time my friends fiancé did all he could to help her by paying for lawyer and making sure she had everything needed while wrongfully incarcerated, when she finally got out she moved back with her fiancé and were like they're old happy selves again. But the only problem they had was he does not like going to bars because he doesn't drink which led her to meet some 39 year old man who is 17 years older then her. She again left her fiancé to live with this man who does nothing but takes her out to bars, she even stays at his house for days at a time during the week and all this man does for her is buy her drinks and cooks for her and his 17 year old daughter. They then just lay around and sleep together and then in the morning drops her off at her ex-fiancés house. Her fiancé still takes her to probation and pays for her fines to keep her out of jail and i think that if this man really cared about her he would be the one to pay for her fines to keep her going back to jail. Her ex fiancé still loves her so much that he puts up with all of it because he still wants to be with her. Im just looking for some advice to try and help my friend realize that this 39 year old man is not good for her and is just using her for her youth.

Hi well it sounds to me that ur friend doesn't realise how good she has it wit her ex fiance, he sounds like such a good guy, why would she go near anyone else, i tink the ex should stop helping her and maybe then she will realise that this 39 yr old is def not the one for her, also i think ur friend might need counselling after all the assaults, i think it has affected her in a bad way and that's why she is acting like this. Hope i helped
