Support needed during labour

Ca
I have come across a few articles online over the last few months about how to be a good birth partner and have been emailing them on to my husband.
He said today that he doesn't really read them, that they all say the same thing, that he knows what to do already and that I don't trust him to do a good job.
I'm frustrated that he doesn't read them! I read them thoroughly and found they described exactly the sort of support I feel I need in labour.
I have no doubt about his capability to physically be there offering practical help, I could do with some reassurance from him that he gets the  the emotional side of things where I will need encouragement, help keeping calm and need to feel safe, loved and relaxed.
I'm not sure that he assigns those things any importance. I'm going on how he acts it I'm ill or upset generally.
I'm worried that when I'm in labour he'll be more likely to be arguing with me about the contents of my hospital bag than helping me keep a calm environment going!
Any ideas for how to deal with this? 
Please don't suggest a doula because I don't have the money. My husband really wants to be there so I don't want to stop him seeing his son born and I don't have anyone else I would want as a birth partner.
