While there are some good suggestions, prayer is the first and most important thing to do. You can ask everyone for advice, but if you don’t ask God what He wants, you will fail. And should God want you to have a relationship with this or another woman, prayer needs to eventually be a focal point of your relationship. Prayer is the beginning of all God-centered relationships. If praying for this person or whoever God wants you to befriend and eventually marry does not bring you peace, then this is probably not the right person. I’d say pray for this person, and see where it leads you. If praying for this person brings you peace, then God will lead you to the next step.
