ok, I don't get my aries ex anymore

So, my kids put me on snap chat. I'm new at it and don't really know the ins and outs of it yet.
About a month ago my aries and I split up again. This time I don't want to go back. He has become verbally abusive and I'm afraid if I let it go then it will end up becoming physical.
We have a mutual friend that comes and hangs out with me and the neighbors. He informed me that my ex watches my stories on snap chat.
I had forgotten he was even on there and didn't know how to delete him until the other night. He is no longer on my snap, but my question is, why is he even watching them?
He told me he didn't want anything else to do with me, so why keep up with me?
I've deleted him on Facebook and now snap chat.

It's called morbid curiosity.

It does give me an odd feeling. Needless to say, he has been deleted now and can't see anything I'm doing unless he looks down the road

Well since hes running and telling his friends... he might just have feelings his moon is one of the best indicators to tell. But you seem curious too. If you dont have feelings for him ignore it and move on cause he will soon get the picture.

I am curious. Curious as to why he is interested.
