Boyfriend (32m) of two years has been distant and closed off?

His sister is going through a nasty divorce and he has been distant. I gave him space ( not really expecting him to text) and he took time off to deal with stuff at home. We have been tg for 2 years and this is the first time we had something like this happen. Before this, we both are in residency he would still make time, but now its nothing. I asked him if we could periodically check in and he agreed, but then didn't follow through. He kept saying he would tell me what was going on, but he hasn't (and I'm not forcing him to tell me personal things about his siblings). He said he would call and then didn't. I want to be supportive, but I don't know how to especially when he's not talking. Any and all advice, please! Do I periodically text him saying I hope you're okay, I will always support you, do I let him reach out etc.
