Why do guys keep a girls number in their contact but never contacts them?

Anonymous
I notice that guys that I used to date or talk to will still have my number save on their phone when they stop talking to me in general. I will get a random text from them like a 1 or 2 after they stop talking to me. Wonder why guys do that with girls they used to talk to and dated.
