<human>: Can you provide a brief overview of the text?

Some of you may remember me and my parents from a previous post about Thanksgiving a couple months back: [Original Post] 

This is not an update, but it is along the same lines in that my parents don't want my boyfriend around. You guys gave me wonderful advice last time about how to handle the situation, some I'm back for more. 

My grandmother is actively dying right now. She will likely be gone by the end of next week. I would dearly love for my boyfriend to come with me to the funeral because I don't feel like I can handle my parents and a funeral without some emotional support. Also because he is quite fond of my grandmother. 

He has known my grandmother since we started dating and though she has Alzheimer's she always remembers who he is and adores him. Last time we went to visit her she forgot who I was, but knew him by name and that he had recently graduated college. Asking him if he had a job lined up, where he was living, etc. So it isn't as though this is some random woman to him, he also cares about her a lot. 

I know what's coming though because my sister hinted at it over the phone. My parents are not going to want my boyfriend to attend the funeral and I'm afraid their going to make a huge issue out of it if he does come. I'm going because I care a great deal about her and being there for my siblings, but I don't feel right going without my SO. He told me he would of course be coming to the funeral with me (I asked just because he hasn't seen my parents since they disowned me and wanted to make sure he was comfortable with the idea). 

What should I do about my parents though? I don't want them to cause a scene at a funeral. I know it isn't my job to make sure they behave well and that they don't have a monopoly who cares about my grandmother and who doesn't. Should I tell them to shove it when they say my SO isn't invited? Or should I accept that I have to go this alone so as to not rock the boat?
<bot>: Grandmother is actively dying and my sister has already hinted that my parents don't want my SO to attend the funeral. Tell them too bad and have him come anyway or accept that I'm going by myself?
