It’s hard to know what the best way to propose to someone is without really knowing them, but a great way to find out is to ask her best friend(s) or her mother or sister (if she is close to them/has them) for input. Another idea is to start having conversations with her about likes and dislikes in general and get her sharing and talking. Also share yourself so she doesn’t think it’s going anywhere. Get an idea of what she really likes and enjoys, if you don’t already know and incorporate that into the proposal. One off the wall idea is to propose to her during a movie trailer on a date night out.
