<human>: Can you summarize the given text in a few sentences?

Backstory:

My in-laws are moving to be closer to us.  They have actually been staying in our house for the last five-plus weeks: The plan was, be here when our second child is born on Valentine's Day, then return home to finish packing, then come back and move into new house.

However...shortly after our daughter's birth (but before they returned home), my 65-year-old father-in-law has what we are terming 'an episode'.  He was out with my 63-year-old mother-in-law when, for whatever reason, he passed out twice...falling on his leg, breaking it in three places.  Then in a follow-up visit with the orthopedist, he announced "I don't feel well" and went completely blank for 45-seconds...an incident that led to four days in the hospital.

He has a walker, his leg is healing, the doctors found nothing seriously wrong with him...and he won't get out of my recliner.  Meanwhile, my MIL got their old house packed up and sold and has been back for a couple of weeks to help.  But they're supposed to close on the new house Wednesday - and he won't even get in the car to go to the closing.  My MIL and wife are working on him but he's intransigent.  Apparently, he's afraid of falling or passing out again due to the stress.

How can I help spur him along?  I want to say something like "You married your wife 33 years ago.  This is the most important day of the rest of her life. She wants you there, you go."  I want to give him a 'be a man' talk - but I'm smart enough to know it's not really my place.

Any help would be appreciated.
