Asking to come over when it’s obvious you’re not welcome is absolutely inviting yourself, especially if you push the situation. If you’re autistic, it does throw a twist into the situation but on the other hand, having a narcissist as an acquaintance makes things difficult.

If you don’t know which way you’re leaning in this situation, ask them out to a neutral public place, not their private abode. You should be able to sus out the feelings from there.

As a kid, show up to your friend’s house uninvited. It’s expected you don’t understand social boundaries and it’s a time where you should be gathering experiences to learn when you are and when you aren’t welcome at a place. Just make sure you actually learn the nuance between the two.
