This is a good question.
For all i read, i'm also an aspie. I have a diagnosed sun (6 years old) and a daughter (11) who may, or not, have asperger's syndrome.
When i was younger, i never felt the need to be a mother. Even after married, it wasn't that important. When my daughter was born, i wasn't sure i loved her, at least not enough.
I had to wait until i was divorced and i had not only the responsability for my kids well beeing, as also for their happiness, that i realised they're the most important thing in my life. And that i don't want to live without them.
If that ins't love, well, what's that? It's worth to be a mother!! !!
