Through social media mostly (Friends Reunited and Facebook) I have got in touch with old school/uni friends , old boyfriends, and a cousin, who I haven't seen for 43 years. I have no ulterior motive, eg rekindling an old flame, as I'm happily married and have 3 married children and also lovely grandchildren. I also had no expectations of any of the contacts becoming close friends. I have had mixed results, but in particular I am delighted that my cousin is very pleased to have the contact with me, and we are getting on really well, exchanging news about family and hobbies. Meeting up with her would be great one day. Only one former boyfriend has maintained contact, and he is happy to swap news about his family etc. Some of my girlfriends have kept in touch, some are not interested, and that doesn't bother me. I think, overall, getting back in touch has been good for me, helped me to see that "where I am" is fine, and has reinforced my general happiness. So I'd say 'go for it', you have nothing to lose
