counterpoint,
“I want you to come” could bring a lot of pressure to the person you’re trying to invite. They might come to the event even if they really don’t want to, just so they don’t disappoint you.
“You can come if you want” gives them a chance to decline if they want to, without feeling guilty.
the resolution can be:
“If you’re available, I’d love for you to come.”
“If you’re free, I’d be happy to have you there.”
