I'm the same. It's not just you.
One of the reasons I never tell friends if something is troubling me is because I could honestly kill those who've spent the evening asking me why I'm a bit quiet and not the usual life and soul of it, wheedling out of me what's wrong, I've finally given in and told them, only to be met with "that sounds difficult" or "what are you going to do about it?". No shit Sherlock! And if I knew the answer to that I'd be bloody well getting on with doing it, instead of moaning about it! Aaaaarrrgh! It really brings me down, when all I wanted was a break from thinking about whatever-it-is and a bit of fun with my mates 😭 . It's just an incompatibility. There's some friends I only hang out with now if I'm on top form. I stay away from them if there's something gone wrong in my life. They obviously can't handle me being a bit quiet.
On the rare occasion I choose to talk about something with someone close, I'm absolutely wanting to hear their thoughts or ideas for potential solutions.
As for all those saying, "but maybe they just need to talk and be listened to if they're going through a tough time"... yeh, ok, I get that - but that's what counsellors, therapists and helplines are for. I'm not interested, willing or able to listen to an incessant litany of woes every time we meet up or talk through the exact same problem endlessly, just because they've got no partner or family to complain at and I'm too polite to tell them to STFU. I expect their next complaint would be that I appear to be ghosting them and they've got no idea why, haven't done anything wrong etc 🤨
I'm single, estranged from toxic family and live too far away from the others to have developed any close relationship with them. So with those in that situation, their situation is no different from mine. I'm busy dealing with my own life, including my problems when they occur and I don't have emotional energy to spare to be someone's unpaid counsellor.
I got sucked into that too often when I was younger, because contrary to what some of you are probably thinking, I am empathetic and a good listener. But I didn't particularly want to do it then and I definitely don't want to do it now. I feel I've done my time being everyone's shoulder to cry on. I seemed to attract that type unfortunately, lacking boundaries myself I suppose and because they needed someone I felt obliged to be there, even if I barely knew them - I'm not heartless and I do care if people are suffering.
I've put a lot of effort into myself and improving my life, I didn't do that so I could be dragged back down by the miseries. With age and life experience I've come to realise that with a lot of them it's almost a choice, to focus on a negative mindset like that and to not take any action, preferring to offload on others every chance they get as a way of lightening their own load. In the second half of my life I want to focus on doing the things that brings me joy and the people that wants to do it with me. I also found that the worst moaners were the people least likely to be there for me if I had a problem of any kind or needed a small favour. So the argument about friendships being reciprocal never really applied to them.
I wonder if it's because life is so online now that those who want a whine don't get those small daily interactions any more, so instead of moaning to ten people briefly who they bumped into in a day, they're now moaning at one friend at length when they meet up every two weeks 🤷
