People on the prowl for a mate don't seem to stay any one place for long. If they don't get a bite in a short time, they move on.
1 or 2 people waiting up to 10 years is not a strong enough argument, I believe. That's more like even a broken watch is right twice a day. It may happen but can't he counted on.
I've been here since 2011, and while I wasn't openly prowling, I did hope to meet someone (though that wasn't my main reason for being here, either). All these years later I'm still unmarried.
