I don’t know who you are or where you’re from or what kind of person you really are but honey, if you realise someone doesn’t give a **** about you, it is time to take a step back. I know it can be hard because of what that person means to you but in the end you come first. Your wellbeing comes first. If someone can’t reciprocate, you’re not at fault. The world is filled with high class A-holes. Hang in there and have faith.
Hope whatever you’re going through gets resolved! X
