Most Helpful Girl
It sounds like with Him masking you feel 'Very Stalkerish,' he is also Missing the Kissing and can't get you off of his mind, out of his site and haunts you to let you know he is till around, day or night on Social site.
It may seem 'Creepy,' but so far I do not see any harm except invading your privacy. However, what is more Disarming and Alarming is when he Loves you and Leaves you and has this Full circle Problem pattern of letting history repeat itself.
If you are finding a way for him to go away, then I am sure he will Get the hint with no hymning nor hawing that you want to Just... Forget.
Good luck. xx
