Sure, I am! I know they like me, and they know I'm aro and have been fine with that so far. We're dating, and I'm okay with that even though I don't really feel romantic attraction to them (I found out I was aro after we started dating). You could also be interested in queer-platonic or alterous relationships. Some people view the two as different and some don't, and that's okay. It's also okay to just have friendships if that's what you find you want.
The point is, there's no one way to do relationships, so as long as you're potential partner/partners know that you're aro and are okay with it, then yeah you can be aro and have a relationship! I hope this helped :]
