do you keep contact information of your past partner?

Hello, there is no way I would want to be in contact with my ex-husband. We did not have a good parting at all. It has been 11 years this month since I have seen him or even spoken with him. I have no desire to talk to him. Only an ex-b/f I would even talk to is a really good friend of mine still and my b/f see's no reason to even be jealous because he was in my past life.

The only reason that I kept his information was because I knew that he was not going to make it an easy break, because he is crazy and a very angry person. So I knew he was going to call me anonymously, and so it was certainly helpful to have his phone number to call and confront him, and when he came to my parents a month after our break up, it was helpful to have his fathers info to call him to come and deal with his drunk and irrated son, also my ex. If I had a normal ex boyfriend, I would have gotten rid of everything, but unfortunately, I did not

No thank you. We parted angry, and I had to find where she had taken my children. After she ripped all my possessions off, I didn't see her for twenty odd years. Last Christmas at my daughter's house we crossed paths again. She has had another failed marriage, and I was pleasent to her. My children told me she used to say horrible things about me, so I have no reason to be nice to her, let alone keep in contact.
