Ex keeps coming over the years...

I have an ex girlfriend. Years ago we got envilved in a very toxic relationship, so I decided to go no contact... 7 years have passed, and she tries to make herself present in my life sometimes and then disappear again... Lately, she came around again... I can see she is the same selfish person I left years ago. I have moved on and now I got married with a caring and lo in person, and I realize that I need my ex narcissist to get outta my life forever! I blocked her in every social media and also e mail... But she stalks to me... I'm kinda confused, all I know is that this person did a lot of harm. And confusing to me so... I think it must end.
