The real-world correlates to love are not a joke.
Songs, movies, advertisements, and commercials are a screwed-up myth.
Once upon a time, I was a hardened cynic about romantic love, and my AS boyfriend knew nothing of it but the idealizations of love in the media and the idealizations of other people in his infatuations.
But both of us are discovering that love and intimacy are idiosyncratic - their form, intensity, and how that intensity manifests all vary with the specific individuals in the relationship.
Someone here mentioned cultural difference. Indeed, not all cultures have any kind of standard or ideal quite like what Westerners call romantic love relationships. But all cultures, all people really, have the capacity to relate to other beings in a way that we might call love, even though it isn't necessarily like media love. Interest, loyalty, devotion, and simple enjoyment of one's time with the other being could all qualify.
Whatever type of intimate connection works for you - if it is in your nature to have intimate connections, as some people do without them just fine - may or may not resemble conventional romantic love. That doesn't matter. What matters is what each being gets out of it, and puts into it.
I don't really give a care how normal my relationship is, even though I'm NT. I don't think I could do a normal relationship, with all the sexual junk and emotional over-the-top-ness. Not at this stage in my life anyway. That's a big part of why I chose my AS bf as a "romantic partner," if you want to call it that, despite the fact that it doesn't fit all the romantic stereotypes. He wasn't conventionally sappy or ready for sex either. So we were able to develop our own kind of thing, spontaneously. We don't have sex (both of our choice), we don't kiss (my choice - he likes it, I don't), we don't say "I love you" (both of our choice). We don't need to. What we have works.
