Half in and half out... How do I move forward?

[barnaby]

I have been working on being more efficient around the house and family. It's twofold; it leaves less for him to do after work, and it's working on me socially-I have previously left him to do a lot of things because I hate talking on the phone and at times I can be cripplingly shy.

So the car needed repairing. He got a couple of quotes; I decided to book the car in and get the right part ordered in preparation. I know a little but this is really his area of knowledge. I had to go back and forth a few times between him and the garage to check some of the car specifications and got it all booked in for today.

He called up later in the day from work after I texted to let him know and double-checked the part was correct. He said it was a right mess; said I'd made a mess of something that was easy to sort out because I missed a letter off the part code and had potentially asked the garage to order the wrong part.

I was really upset. It took a lot to make those phone calls, and I did it because I knew me doing it would get it done sooner and save him a job in his free time. My reaction was to blow up and then cry,that I can't seem to do anything right at the moment, but I played it cool, he said he'd sort it so I said ok and left it at that.

I wasn't sure whether to say anything when he got back, but turns out he didn't sort it and was just going to take the car in on the way to work. I got a phone call earlier with him joking that they HAD ordered the wrong part and it would cost 4x what they quoted- turned out it was fine in the end. I laughed along.

I don't know if I handled it right. The last thing I want to be right now is some emotional wreck who gets worked up at the tiniest thing, but I didn't appreciate how he spoke to me on the phone. What would have been a good way to address briefly and to the point AT THE TIME how he spoke to me? Should I have explained my good intentions or left it?
