<human>: We've been together 2.5 years, lived together for probably 1.5 yrs of that. We're very serious about each other and both want (and have discussed) the future in which we get married and/or have kids. 

His mother has a 10% chance of survival past 4 years and this news has been absolutely devastating to us. I am very close to his parents (I don't speak to mine) and he is an only child so they are quite a tight knit group (which they have graciously allowed me into). I feel like I have a real family now and know for sure that I want to have children so that they can experience being grandparents (on top of all of my own personal reasons of course). 

His mother has mentioned once kind of half-jokingly that it would be better for her if she could have something to live for, like us getting married or having a baby. 

His dad doesn't really have anyone else and a grandchild would certainly give him something to be happy about if worst to comes worst. (That sounds horrible. Maybe this really is a crazy stupid idea...)

Anyway, one more large spanner in the works: BF and I live a continent and an ocean away from his parents. He's gone to stay with them for an indeterminable amount of time. I visited for about a week and then had to come back home for work.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: BF's mum has aggressive cancer and a low chance of survival. We both thought of getting married and/or having a baby and I'm starting to think about it more seriously, am I crazy?
