My friend has been single for 9 years. Before this she was in a 9 year relationship and she would ask the guy about marriage and he kept telling her he didn't know if he wanted to get married or he wasn't ready. They never got engaged. He was quite controlling so she didn't see her friends. He ended the relationship and got married to someone new 18 months later and a year after had a baby!
In the past 9 years she has re-added my ex on to Facebook just so she feels close to her ex even though my ex and her ex fell out and no longer speak. I'm annoyed as my ex was a domestic abuser to me and she knew all this. This was in the days before the government got stricter with the law and there was more awareness on these relationships. She also added my ex's, ex girlfriend who he had sent inappropriate messages to while we were together - I think she re-added in lockdown after not speaking to this woman in 15 years. There is another mutual friend too who sends her inappropriate messages and she deletes and re-adds him every few months. It's like she enjoys the drama and cannot move on from 2004 to 2012 when she was with this ex and knew all of these people.
She has recently started dating a guy she knew from school. She said she wasn't keen on him but he will help her move on. I know it's not my business that she wants to maintain these unhealthy relationships but what concerns me is I don't want my ex and his previous ex to know about my life nowadays. Most people I know move on and make new friends and not go back to the drama. I don't know if she has depression.
