M, I think you did fine. There was a charge against the business account and you had a legitimate reason for checking on that. Let's hope his answer is legit.
He probably responded with the petrol charges because he knew why you were asking about the flowers. A little tit for tat, if you will. Brush it off; he's just reacting because he knows he's been an Azz and wants throw all the blame onto you.
If his reason for the flowers is legit; it proves that things aren't always as we see them. This is one of the reasons for the 48 hr rule; wait that long before reacting to what you see. Man, I wish I knew that one some time ago.
I think the strength you feel is that you were able to go in and talk to him about what concerned you. You came away a little emboldened because you survived it and hopefully your suspicions turned out false.
You're on the right course with no calling or texting. It's good that you've got plans. More and more of these types of plans and you WILL be GOOD company.
