Normally I can sense that easily with a girl. If she wants to be just a friend or a "romantic friend" like you say.

But with that girl, it's just more complicated. And trust me if I knew she did not want me, I'd leave her alone.

For some reasons (bad karma, probably ) each time I try to get close to her something happens and prevents me.

The other time it was her drunk friend. She was "stuck" to me and would not leave me alone.
