I don’t think you’re doing anything wrong in that case. It doesn’t always work out, and it can very frustrating when you think it’s working out and it blows up in your face (or just disappears entirely)

It’s just important not to bring that frustration to the table next time. And it’s normal to take a step back and say “nevermind I’m not gonna worry about this”

Just keep your head up, man. One day you’ll come across somebody who wants it to work with you, and will make sure does.
