Hi OP, I've been single since I was 30, nearly 20 years here. I've had a couple of short term flings with complete twats but nothing serious or long term.
I've been online dating on and off since 2006, gone on blind dates, done: guitar lessons, salsa, art groups etc etc over the years but not met anyone. One of my problems is that I look younger than my age so tend to attract much younger men that I'm not interested in for a long term relationship (hence the flings).
I've just lived a single life, live by myself, travel by myself, attend parties by myself, go to the theatre, cinema, exhibitions, my birthday, Christmas by myself.
I have given up meeting anyone now. I found OLD soul crushing and hate doing it. As far as I'm aware, I've done everything I can, I've put myself out there, am friendly and approachable. Nada. I've travelled a lot and being by myself has made me far more independent in that I'm so used to doing everything by myself which is great. I have a lot of regrets though, I miss sex and intimacy. I miss sharing my life with someone. I miss having no support, no one to come home to, no one to make me a cup of tea or ask me how my day went. No one cares really. It's very, very tough.
