<human>: Can you condense the text into a few key points?

So my boyfriend and I have been dating for about 2 years. Our relationship on the whole is great. Lately he's been having some family trouble and I'd like some objective opinions on what I can do to help.

5 weeks ago, he found out his parents are getting a divorce. This is not a huge surprise (they have told him they are getting a divorce several times before, but it looked like they had gotten past that). He has been in close contact with his Dad, but he has only spoken to his mother twice since he found out. One of the times he spoke to his mother it was just because he needed to pick up some stuff from her house as they are selling it because of the divorce. He blames her for it and will not talk to her or either of his half siblings, who he thinks helped convince her to get the divorce.

So three weeks ago, he found out his maternal grandmother has cancer.  He is afraid to go over there because he might have to see his mother or talk about the divorce.

Two weeks ago his niece was born. He has not gone to see her, as he has not talked to his half siblings since he found out about the divorce and does not want it brought up.

I don't know what to do here to help him. We have agreed that these are not issues that will magically go away, and he needs to talk to his family and definitely a counselor about these issues. He says he doesn't have time to talk to anyone about this, not me, not a counselor, not his family. He is refusing to speak with his family about MAJOR life events. I feel like this is completely inappropriate. At a minimum I would like to get his Grandmother a card and some flowers to show sympathy for her cancer and offer our help, and I would like to get his SIL something to congratulate her on the baby. He does not want contact with any of his family for the reasons above and will not give me their contact info to at least acknowledge the situation.
<bot>: Cancer, divorce, and a new baby. SO is excluding us from all of them, is it over the line to expect that I can at least get contact info to give flowers to cancer patient and new Mom?
