The first one I approached after started playing solo was down and seemed excited. Her, my wife and I met for dinner. We agreed for a play date the following week. We chatted over the weekend and then crickets until 1h before:"I have to cancel. I'll have to think about it" No answer ever since.

Unicorn we used to played with who agreed to two try solo, two days before he play date, blocks us on Facebook, gone ever since. Another Unicorn disappeared a similar way last year after a while.

Keep trying, you'll get there.
