I’m guessing I’m meant to be alone

The word ‘standard’ is completely wrong in this context. You either love a person or you don’t. It’s not like you would rate every girl you meet by some arbitrary standard and then date whoever has the best rating. Love doesn’t work that way. I’d go even further and say that most people’s standards (if they have any) are superficial at best and concern no character traits which are actually necessary for a trusted relationship.
Don’t say you have to lower your standards to include even the ‘worst kinda’ girls as if those girls were less worthy of a great partner than anyone else. Just as a sidenote: Girls regarded as “low standard” by what most people think actually are more loving and caring partners most of the time. It’s very similar to the difference between people who have experienced depression and those who haven’t.
That’s the problem with schools: They teach young kids standards and values which are complete nonsense and they aren’t able yet to realize this. It’s not even the teachers fault but the way in which children interact.
Anyways, good luck with finding a girlfriend. And even if you don’t fully get what I wrote I still hope you realize its importance in the next years.
