Cabbie,
You seem to have assessed your problem very well and yes, you need to have 'that' conversation with your H. To varying degrees, many of us have had similar 'post retirement' issues..
Unless I'm mistaken, it's very likely you continue to take care of most of the household obligations. Now that HE'S retired, he's enjoying what he feels is a well earned, well deserved 'Permanent Vacation'.
The trouble is that unless he has plenty of hobbies, he's probably bored out of his mind by now and can't figure out what to do with himself. You, in the meantime continue to fill the role of housekeeper, personal valet, cook, courier etc., whether he goes out to play or sits idly by, and it's business as usual.
He should be reminded that even after retirement, he is still responsible for contributing to the household, even if it's in a different capacity. He should be mindful also, that if you're both living, eating, spending and working together under the same roof, that you also share the workload equitably.
Most importantly, he needs to realize that those (household) obligations are his responsibility too... and that he's not the only one who is retired....you BOTH are!
