Is it over for me?

[Yoyowife]

Okay I have a question for all of you experts. My H got mail, a bill, here today. I debated on calling and telling him. I was just going to wait and let older D take to him when she came home from college this weekend. I decided that might seem a little hostile and obvious so I just called him. I told him I just wanted to let you know that you had a bill from XYZ Co. He said oh yeah that's where I had to get some work done on some equipment. I said okay just wanted to tell you that. He said okay and I said bye. I did not engage in anymore conversation. Exchange was pleasant. Did I do the right thing or should I have asked him about his day? Is this a good form of detachment? I haven't done very well in the past, so I need some good advice.
