Life, maybe Steve is concerned about his own career and financial situation and either he wants to see if he will have the support that you had or he wants to distract himself from his own depressing situation. I suggest that you take a wait and see approach for a week. If his attitude doesn't improve, follow KSig RC's friendly approach.
Another idea, maybe it isn't Steve at all. You still owe people money. Check in with them and see how they are doing financially and career-wise. Make sure that they are still fine with the terms of the loans. Maybe they are in the same boat as you were a few months ago and could use that money now. I hope that I am wrong, but he could be voicing someone else's concerns. Also, could it be possible that you owe someone else money and forgot?
Or maybe you should just kick his a$$.
Just kidding!
