Boyfriend's ex wants him back?

[Help]

The story is going to be lengthy. But please be patient.
Once my bf (before we met) started receiving calls from a stranger girl saying she loved him. She started threatening to commit suicide if he doesn't lover her. Once day she threatened to burn herself if he doesn’t say he loves her. My bf was scared and he ultimately said he loves her. (I have confirmed that this is a true incident).
My bf acted to love her.
Once my bf called her at midnight and found her in "call waiting". This happened several times. When he asked, she crying and damaged her phone, and sent it to my bf on courier. Fortunately, my bf is smart in repairing mobiles, which she didn't know. He repaired and retrieved the data in the mobile. There were adult messages in the mobile. Her call history also showed that she used to talk to others for hours at night.
My bf questioned her about the same. Then for a month, she didn't contact my bf. Then she called again and said sorry and confessed that she was actually talking to others as well. And then she told him that she was an orphan.
When he came to know that she was an orphan, he empathised with her. And gradually he started falling for her. Then he forgave her and started loving her. They remained lovers for about a year, after which the same incidents started surfacing again. She was found in "call waiting". She was frequently lying.
They again had a fight on this. One day her sister called my bf and informed him that she tried to commit suicide and is admitted in hospital. My bf was scared.
The next day my bf received calls from the girl’s cousin brothers. They threatened to kill him for their sister's condition. She again started contacting my bf from the very next day. But he didn’t show any hatred towards her as he was scared of offending her. He has a family to support. If something happens to him, his family will perish.
Then from one day, this girl stopped all contacts. She changed her number. Though the girl has actually cheated him, he still had sympathy in his mind because she was an orphan.
During this one and a half year time, he believed that she has gone forever. It was at this time that we met. He proposed me. We loved. And them one fine day this girl called him from nowhere. She said that she didn’t have a phone for the past one and a half year, so she couldn’t contact him.
SHE WANTED TO REKINDLE HER LOVE WITH MY BOYFRIEND.
He was shocke. He told her that he loves me. She was furious. She started threatening again. When I came to know about this, I was in utter confusion. (Every time she calls, my bf puts the call in conference mode with me, without her knowing). When I heard her crying like hell, I couldn’t stand it. I told my boyfriend to accept her back (because I found myself responsible. I didn’t want to snatch him from her).
But he was not willing to. He wanted me no matter what. Then I got her phone number from him and called her. I didn’t want to hurt her either. I said I was just in for a time pass. I also asked my bf to act nice with her. He agreed to it on the condition that I wouldn’t leave him. Then we decided that he would act nice with her and try to make her understand that they can never be together. (Two religion, two caste….. and both families will never agree. And my bf had lost faith in her).
Once he asked her Facebook password. She kept giving clues but didn’t tell the right one. But both of us tried and tried and guessed out the right password. She didn’t expect.
We saw that she was having adult talks, and also sending photos of her nude body to other men.
My bf was again broken. He couldn’t stand it. I too was shocked. I had always talked in her favour. When he asked her about it, she again changed her number. Then for about 6 months, there was no contact.
Last month, she called again. Said she want him back. I was furious. I was not ready to sacrifice my love for this lady. Then she started creating another drama.
He still pities with her as she is an orphan. He told me that it is the only reason he loved her and the only reason he can’t forget her. But more than that, he wants me in his life. He wants to marry me. He is scared that she would kill herself. So now we have somehow convinced her that we don’t love each other.
It hurts a lot to disown my love. She called me yesterday and asked me to stay away from his life. And she has been sending messages that they are together at night…. And all such messages to provoke me. I just keep silent because I know the truth.
Every time they talk, even now, he will put the call in conference mode with me without her knowing. I hear her saying lies about me. But my lover trusts me. I am thankful to God for that.
But I am really broken. I can’t see a girl trying to flirt with my love, and all I can do is just keep listening…
I need a solution. Please help.

Too long, didn't read.

If they're broken up, then there's no reason why he should be speaking to her.

If she's depressed, then it's not his responsibility to "fix" her. He needs to tell her, ONCE, "We are not a couple anymore. Please stop contacting me." And then he should block her phone number, email address, and everything else.

If he believes that she's suicidal, he should call the police and her family to inform them that she needs help.

He is NOT responsible for her well-being. He's with YOU. You both need to ignore her. If he cannot stay out of her life and ignore her, then you should break up with him.

i read whole of it and to my thought what u can do is very simple.

You ppl (i mean u and ur bf) change ur email address, contact numbers, scrap ur facebook profiles. Give her no clue about urselves.

If this is not the option then register a police complaint or get urselves married to each other.

If u or ur bf doesnt agree to any of these, then apparently u will lose ur peace of mind for many many days to come.

I skimmed through most of this, but it doesn't matter, because it's so obvious. Your bf needs to break the hold this girl has on him. There's lots of ways he can do that, but until he does, you don't have a bf.

Explain this to him and break up. As long as he allows her drama in his life, it also rules your own, and no sane person would allow that.

When I first created this site I wanted to create the best online resource for getting your ex back. So far, I feel I have done a decent job of that. However, as I started interacting with you I began to notice that what I was writing wasn’t enough, you wanted more. This was especially true for those heartbroken women whose ex boyfriends have moved on to a new girlfriend. I understand how you particularly feel because I have interacted with so many of you. So, I decided to do something I have never done before.
