I'm starting to get a picture of someone who's so malleable, he feels obliged to go along with anyone who expresses an opinion
Hence, anybody trying to actually persuade him of anything would be perceived as controlling? If he is like this, he must be a salesperson's dream!
An alternative interpretation, I guess, could be that he's so up himself he doesn't really believe anyone has the right to an opinion different from his. Or, perhaps, any woman.
Love the getting genuinely ill when faced with a difficult question! My XH2 did that as well! It was so obvious, I wasn't very sympathetic: I reckoned he should have learned to handle awkward feelings some time before growing up & getting married. He found plenty of other women people to fuss over his symptoms, though. As far as I know he still believes he's got a heart condition (they were panic attacks.)
Good to hear you had a lovely time with your friend - and her squishy baby! The ones you can play with and then give back are the best sort in many ways 
Are you feeling better about going to work tomorrow?
