There are some people (especially those who are very much non-INTP) who will say it's bad to become friends with someone you want to date, as if becoming friends first ruins that possibility. That may be true with some people, but I'd guess that anyone who is (or who seems like) an INTP is not the sort who will close the door on being more than friends just because you've become good friends first. So, I would recommend just trying to show interest as a friend at first. (You're not in a rush, I hope.) Given enough time, friends who are attracted to each other will figure it out, and it certainly will lead to better things rather naturally. But if she's not attracted to you, you'll likely still come out ahead having become friends with her, and however bad it feels if she doesn't have similar feelings for you, it probably won't be as bad as asking her out on a real date before becoming friends. If she becomes your friend yet never more, she will likely help you understand other women better. Back in the day, long before I was married, I had a lot of friends I wanted to date. They didn't seem to have the same feelings for me, but even so, it's nice to have good-looking friends. Good luck though. Hope it leads to more than just friendship.
