Stop talking with him about your relationship. Take the tests and pass them. Finish your medical studies, and when you get liscenced them leave him without giving any warning.
He is using you, and you are using him. When you are less dependent on others, and more capable of supporting your own dreams, then you can have love to offer and be able to freely accept love. Until then, you are both each other's slaves.

Very good advice, spotsy. Direct, to-the-point, honest, and helpful. Well done.

Be well,
RS
