<human>: Kyle(22m) and I(22f) attended the same school and graduated 5 years ago. We had the same social circle, but were never really friends.

Since graduating I've seen Kyle maybe three times(I helped him move some furniture, bumped into him at a concert & he came to a farm day with me and my partners that I posted about on FB) We're not close at all, and while I don't dislike him, we have nothing in common. Without meaning it harshly, he's a "nice guy". He drifted apart from most of his friends towards the end of school as his then-girlfriend had some legal problems and he got really absorbed in her drama.

Recently, his mother died(long term heart issues, she didn't survive her second heart surgery). He's now caring for two of his younger half-siblings, their father is not in the picture(I think he's in prison).

He's been reaching out to build a friendship with me, and others. I've invited him along to some social stuff, but he is pushing to catch up in the evenings & weekends. (I'm 35 weeks pregnant and working, I'm a zombie in the evenings and my weekends are spoken for - although I've invited him along to weekend events where I can)

Tonight he asked me to be a "reference" for him, I don't know what for. I've barely seen him in years. I told him I'll be his reference, but that I don't think I'd be a good reference as I've never lived or worked with him.

I'm not in a position to be his emotional support, but I feel awful that he's in such a difficult situation right now. What can I do to support/help him? I've gotten the impression from him that none of his old friends are standing by him. I also don't know anyone(aside from my grandparents) who has died, or known anyone with relatives who've died.

Can you condense the text into three sentences or less?
<bot>: Old acquaintance from school's mum just died. He's left caring for his younger siblings, I don't know how to help him.
