You can tell by how she acts when you’re together. If you feel like she enjoys being with you, there’s a good chance she’s interested in you too.
Just keep courting her and put in more effort so she can appreciate what you’re doing. After a few months, around three, and there’s still no clear answer, you can ask her what your status is with each other.
Tell her you’re not trying to rush things, but you’ve been courting her for months and you just want to know if you have a chance or if you’re just waiting for nothing.
