Leave him who make u feel to die.
This happens when you emotionally attached to someone. But, this doesn't mean you have to compromise you mental stability and health. First give some space and set some boundaries with your boyfriend. Do not overthink about him and relationship. Take out time for your other people. Then don't be always dependent on him. Stop over expecting from each other. You both need to give each other clearity on what you both are expecting from this relationship. Try to find happiness in small things you do and keep smiling 😊😇. I hope this shall too pass.
