If he has always been good with bills and money perhaps he really is having a hard time financially. Of course, if that is the case it would be nice for him to let you know the checks will be slightly delayed.

Otherwise I would just go about your business and if the checks do not come pursue the avenue you need to, to get them. What about a direct deposit so nobody has to worry about sending stuff through the mail?

These WAS take the cake. My H texted me from a concert a few weeks ago out of the blue. It's ridiculous.
