Help! New to this...still hoping for R

[Rusty]

Okay - H just left with S to go to college orientation. I have not spoken to him since Saturday when I called to let him know that the money he put in my account on Thursday would show up today as the bank was having some issue. I was very short with him due to the fact that he tried, when I talked with him on Friday about the money, to make me feel - again - like I was saying he never does anything right and dragging me into one of our old fight issues. I refused to be drug in but I definitely was upset about it. He called back to apologize (several hours later), and I accepted but was not friendly. Then the Sat. call. Haven't spoken since.
He and S are driving to UK, all the prep and any schedule of the trip was never relayed to me, I let them use my car - his is a POS and probably wouldn't make the trip - I made cookies and had some snacks for them to take. My S took my car to his apartment to pick him up and H never called to tell me anything!
I am so angry! I had even thought that if he called I would be friendly and just say Hey - how are you doing - are you ready for a fun trip with S. But I didn't even get the chance.
What now - he has definitely climbed back into his shell and I don't know what to do......
