im friends with SOME of my exes, the ONLY one im not friends with and all is an LONG TIME rival and i will not acknowledge her! otherwise most are netural friends we just don't bring up grudges or plms from the past it's not worth the time of day, we just close the chapter and talk abt netural things, such as sports, poltics and etc. otherwise ofc i do ask some questions related to some personal info for my benfits if i happen forget something related to my health or something related to bills or something then ofc we would talk abt that but it's rare, only my closest friends have those info of me in case in event anything happens to me, my current gf is now getting to know abt my full medical history and thats important to me, same for my gf who is divulging her info too in case anything happens to her, better safe than sorry, but Im always doing backups for myself, so if anything happened to me and they need to contact my family then they have that resources to contact and i feel safe abt it!
