Sexuality is not a strict, unyielding thing. For many of us, it changes over time. Or we may find we are more attracted to one gender, but still sometimes attracted to the other.
There's no right or wrong answer.
There are also different types of attraction. Emotional love and sex usually go together, but sometimes, they don't! Think of an asexual person. They aren't sexually attracted to anyone, but they might be romantically attracted to someone.
Tell her how you feel. Maybe go on a date. See how it goes.
