On her defense, she is a very attractive woman, and now that she is single I'm pretty sure she is swarmed with texts and phone calls from guys all around the planet 😆

To play it safe, text her every now and again because she might actually be busy or get annoyed if it`s too frequent. A reply is always a good sign and a stream of replies is even better if you can get casual conversation started without trying too hard.
You should just act like you always have when you see her, if you have good conversation in person then something must be good. Invite her to things you think she would enjoy every now and again so she doesn`t think you`re disinterested.
