Well, it would be presumptuous at best to try to speak for other aspies. I only know myself and what I'm like, so take it with a grain of salt. Also, my only relationship thus far was with a girl who was incredibly needy and clingy, who probably isn't representative of the norm.
I like to make time for myself, it's true, and sometimes I even like to make a lot of time for myself. That said, I enjoy spending time with someone, and if I'm in a relationship with that person than I am willing to make more of an effort. If she wants me to see her every day of every week, and never gives me peace and quiet to enjoy the solo activities I enjoy, then we're incompatible. If she wants to hang out a couple times a week or so and maybe send a text or two everyday wishing one another a great day and a goodnight, I'm up for that. If she's way too busy to hangout even once a week or doesn't return texts within 24 hours that would also be a red flag.
The bottom line is, I'm me, and I don't want to have to stop being me and bend over backwards for someone. I'd much rather meet someone who's in sync with my life or who at least respects me for who I am rather than trying to turn me into something I'm not. Sure, I may need a little more space than most people, but as long as I can have time both time to myself, and with the person I care about, I'm happy. Contrary to what my ex may think, giving me space while I'm working or doing school assignments isn't me time, nor does wanting time to myself mean I'm cheating. In fact, I'm the last person who would ever cheat. Romancing a girl in a videogame doesn't count as cheating as I approach that purely as a goal in the game like any other, and I'm not giving up games with romantic elements. I'll just float an otome game by my significant other or give her the opportunity to sell her soul to the original Mass Effect Trilogy, and then we'll be even.
