Cutting off

I’m fighting cancer which was diagnosed 3 months later after our breakup which I initiated, even though I loved him and still do. I was alone in a foreign country being a refugee and my ex was the only close person so I let him know. I decided to go back home for treatment and operation, everything went well, still waiting for MRI before radiotherapy, but decided to go back to UK for further treatment. He wasn’t supportive during this extremely difficult period of my life, only checked in occasionally. Now he wants to pick me up from airport. I don’t want to hurt him as I truly care for him, don’t want to block him as it’s childish, but don’t really want him in my life either a friend or partner, as he proved once more his indecision and unreliability.
