I totally understand the stress of "not talking" about things.
My partner was the same way - he wanted to talk about the serious things only in a face to face chat, and while I understand the desire to do it that way, it still drove me crazy having to wait. And as it would be months before we could see each other face to face, I finally told him that it's important to me to have these conversations, and it was really stressing me out not talking about it. He understood how much it stressed me out - the feeling of not talking - and he agreed to have a phone conversation about things. We did, and it really settled me down. And he didn't think it was that bad either. I think he still would have preferred face to face, but the conversation via phone wasn't as bad as he thought it was.
As you only have to wait until Wed, that's not too long to wait and try to find things to keep yourself busy. But, if it would be a longer amount of time before you could have the face to face chat with your partner, I would definitely recommend telling him how you feel - and if not talking is stressing you out, tell him that.
LDRs can be very difficult sometimes, but hang in there! They are do-able!
