Hi jawn,

From what you have described it looks like you still have the energetic cords (ties) of attachment with this person, their family members and their external environment. These cords are invisible since they are at an energetic level. They are also called as psychic ties.
All you have to do is cut the energetic cords of attachment to get it out from your head.

Please go through the below links to know more on what it is-

Calling upon Archangel Michael with his golden sword is a very famous way of cutting negative cords-

There are many ways of doing this. Simply do a web search on “cutting energetic cords of attachment”

Also if you prefer something visual then there are lots of videos on YouTube too.
