Hello Lou, so sorry to hear about you and your boyfriend's situation.  I think that I can help you gain some insight.  Me and my husband have been together for 11 years, and when I was diagnosed with cancer 6 years ago, I felt like I had no right to ruin my husband's life with my illness.  When the time came for me to have chemo, I returned to my home town and am now living with a relative.  My husband was deeply hurt for a very long time, because he couldn't understand why I had gone.  I told him that I wanted him to move on without me and perhaps try to meet someone else.  I told him that I loved him enough to let him go, and this is exactly what has happened with your boyfriend.  I am sure that he absolutely does Love you, but he feels that if he stays with you, it would be unfair to you.  Also, it is highly traumatic to get a cancer diagnosis and it really messes with your mind........you are unable to make rational or logical decisions.  Also, he might need some time alone to process what is happening to him. Why not write your boyfriend a letter and explain to him that you understand WHY he has ended things between the both of you, but you still want to be there for him.  Tell him that his illness has not changed how you feel about him or your relationship.  The reason that I suggest a letter is because it is much more personal and intimate than a text or an email.  What happens from there will be up to your boyfriend, but at least you will know that you did everything you could.  I wish the best of luck to the both of you, x

You're welcome Lou, good luck, xx
