My older sis's currently ex bf is in jail. he is abusive and sends anywhere from 1-3 7pg letters a day. he's always talking about how sorry he is and says thats he is getting help. to her, it seems like a great thing. she thinks that jail will change him. she doesnt understand that when bullies feel weak, they get worse. thing is, she has 2 kids(one his daughter) and is pregnant with a third. she told me the other day that she was through with him, even sent his promise ring to him in the mail. well, i read one of the letters, actually i took it from her mailbox to read. 7 pages saying that he loved her and he was never gonna hurt her again. I know if she read this, she would fall for him. she's read some of the other letters to me and talks about how she misses him and how she wishes he were around. but i know that she's scared he'll come after he gets out and come knocking at the door demanding an explanation. i'm afraid of this too. i just dont know what to say or how to tell her that she needs to get away from him. her son is terrified of this guy, and his daughter barely even knows him cus he always leaves to go partying. he's going to be in jail, this is the best time to get away. he tells her in his letters that she better not find someone else, or that he hopes she wont break his heart. how do i help her?
