I met an amazing person who is against dating right now, but I don't want to date someone else.
Why can't you just keep looking for someone else? Why do you only want to date this person?
I met a person who is allergic to the word ' date.'
If they don't want to date someone you should just focus on yourself. It's not selfish to look out for what's best for you.
I want them to like me and find me interesting.
They may find you interesting, but right now they have said they're not dating. You'll need to wait around for them to change their mind, which could be never, if you want to date them. There's no use in trying to keep pushing them to date you now.
