My ex bf gave me closure months after our breakup which made me feel good. So I asked him to do the same with his ex gf for I believed she hadn't moved on bcoz she had stalked me 3 years after breaking up with my ex bf. 

So knowing that my ex won't talk to his ex to give her the closure I then texted his ex the next day asking her why she had stalked me 6 months ago. She said that my profile was on her recommendations so she merely checked out my Insta story. I told her that the reason I was texting her 6 months after she had stalked me rather than on the very day of her viewing my story was coz I thought she might not have been over him and I felt that I could help her now that I've also broken up with my bf. She said she was over him a long time ago and it's fine. That was it. We promised not to tell our common ex bf about our interaction. And immediately next day my ex bf then texts this ex gf telling her the reasons he broke up with her. He surprisingly had listened to my advice after all &amp;then he texted me that he had texted his ex. 

Now months after this incident that is 2 days ago this ex gf accidentally asks him how was I doing. He then asked her how she knew me. She said we talked but didn't tell him what.

So he immediately texts me furiously asking why had I contacted his ex and said, "why can't you all keep your shit together?" I said sorry and said that I shouldn't have talked with her &amp; that it was way out of the line behaviour from me.

But what pissed him more was what was it that I had talked with his ex. But before I told him what it was we talked he said that he's been very good person to me after the breakup but he won't do that anymore and asked me to stay away from him. He now is ignoring me and also the other ex.
