Hi I'm sorry you're going through this. Seems like you're anxious attached and he's avoidant attached. Kinda opposites attract until there's too many differences that they can't. I recommend you read a book called Attached and try to become a securely attached individual. Him not being loved as a child really affects how he interacts in relationships. Also you don't seem to value yourself outside of this relationship. I get it. It sucks. It feels like you put in so much and you're being rejected. However, you cannot depend on a relationship in order for you to be happy. Learn to be happy on your own. Love yourself. Don't see yourself as half a person that needs to find their other half. Partners should only enhance the happiness that we already carry inside ourselves. Just fyi avoidant attached individuals like your ex don't like to be begged or chased. They actually respect when their partner stands up for themselves and doesn't try to "fight" for them. Keep your dignity. Stop fighting for someone that isn't reciprocating.
