My boyfriend was with me when I was told I have cancer.
I got all the leaflets and gave them to him. He didn't read them. he kept saying everything will be alright.
When he was coming to the hospital to collect me after my op he said it suddenly hit him I have cancer.
His being in denial was very difficult for me. But he is now more involved but terrified of giving advice about treatment. So it's still my decisions.
Only you know what your relationship is like. There is help out there for him, but he has to want the help.
I'm so sorry you are having this problem right now. I can't help but wonder how your b/f would feel if he'd just had a devastating diagnosis, followed by surgery and you became demanding about sex.! Thankfully, not all men are like this. Is it possible that he might read a booklet from this site?
If so, it may make him change his attitude. However, if not, I'm wondering how supportive he will be while you are undergoing radiotherapy or possibly even chemotherapy. I was diagnosed in December 2012, and had treatment last year. I'm certainly nowhere near to being 'back to normal' whatever that is. I know a lot of women would think carefully about carrying on this relationship if it is based on sex alone. But that is your business, nobody elses. But you don't need him being nasty with you while you are feeling so fragile, and further treatment might only make you feel more so.
