rr22 is so right. You are not abandoning him. H does have a phone, if he wants to talk, he can call or text you and honestly have a conversation. He does not have to wait on you. It is good that you didn't answer his first text because he was baiting you into an argument. You handled it well and just contacted him when you were awake and ready to answer. You don't need to answer the "are we ever going to talk" because by you answering him and saying hello, it is showing him you want to talk without ever saying anything.
I know it is hard, but you really do need to wait until H is ready to get some help. Watch for him to open and look up some things he could try to help himself so when the moment is right, you can be prepared.
