FlowerArranger I get that it's frustrating but you're giving the impression that you expect to try OLD and instantly find the man of your dreams.
Sadly it doesn't work like that. I wish it did!
It's a numbers game. Looking for a needle in a haystack time and it gets harder as you get older.
Some very generalised facts about OLD. Women are more choosy and will only "like" around 20% of profiles. This means men have to work harder to get noticed, so they tend to "like" about 80%.
But they won't necessarily be interested in all those women. They will filter out the ones they're not interested later.
How long have you been on Match? You can use Match without paying, so some men that you message may not be active or may not be a paid user so can't send messages.
On Tinder you can write a short bio of what you like. But most people swipe without reading it. Set it up, have a swipe through the profiles. see who you match with and get chatting. Just because they don't mention opera etc, doesn't mean they don't like it.
Maybe they've never been to the opera but would like to go there for a date.
Try POF again. It can be a bit glitchy sometimes and delete profiles for no reason.
I also suggest that you do some research. Google OLD sites for older people, ideas for profiles, how to get the most out of OLD etc.
Don't want to put you off but I've been doing OLD for around 6 years and haven't met the man of my dreams.
But I've met lots of nice men, had some great dates and I'm still friends with a few of them. It takes patience and time and lockdown isn't helping right now.
