Girls.. am I a horrible selfish person?

So it's a long story . Trying to be cut short.

So over the Christmas period my partner was spitting blood, fast forward he was sent to hospital and had loads of scans, they've found lumps in both lungs and his kidney behind his abdomen.. now they're still investigating as to whether it's cancer but the doc says it's a very high chance. This news broke me, and it broke him. Bear in mind I'm his only support and he's mine.. anyway, we found out I was pregnant around the same time.. unfortunately I started bleeding and from there miscarried.. the miscarriage didn't follow through leaving me to take the 4 internal pills to bring out the baby, causing excruciating pain. Now here's where my issue is, ever since my partners health scare, he's been awful to be around, he's always talking about him self, it's always swearing and negativity and treating everyone around him like shit and this is because "he's dying anyway" ( the words are from his own mouth)

I understand what he's going through is scary but the one time I asked him to support me was the night I had to pass the baby, we are currently long distance due to his health, he promised me I could always count on him, he'll be there to support me through this, but instead.. he started to snore on the phone while I was speaking.. I can't help but feel like now that he's been told he's sick, the world revolves around him and he can do what he wants and my feelings are so invalid.. I do everything I can for him, above and beyond, I would walk through fire for him.. seriously heal

Am I selfish for just caring about myself?
