I've known my best friend since we were 7yo, we're now both close to 50. Our lives have known many ups and downs along the way. We live far apart from one another and rarely see each other but when we do we pick up again like we've never been apart. Both of us have had big stuff going on in our lives. Hers was very messy early on, mine has been messy the last 3/4years but has lately settled down. We last spoke at the beginning of the year. In recent months I've txt'd and emailed and had no response. I thought I'd leave it and give it time but still silence. Then I phoned her home and it just went to answerphone. It seems I can't get hold of her at all. I'm sure she knows I've made contact. I'm hurt if she just wants to drop the relationship, I'd rather she was straight with me and just said she's outgrown it or whatever - if that's what's happened. I don't want to make a pest of myself and call her parents (who know me well & like me) as they're very elderly now and I don't want to cause any distress. There have been no 'incidents' between myself and my friend. I don't understand what's happened but it's been months now and she hasn't responded to any of my messages. I'm a bit heartbroken if I'm honest since we knew each other as children. What would you do?
