What text message should I send to her so as not to appear abrupt? Ask for templates and guidance.

Personally, I don't like people always asking me personal questions. If you are friends, talk casually when you meet, and talk about everything, but don't involve the private affairs of girls. You can text her as a friend, a funny joke or something. Talk about miscellaneous things, don't let her be wary. Girls want to keep a certain distance from boys who feel like chasing themselves. Make good relations first, then make good relations, and then slowly ask out to play.
