So both families just met for the first time last night - correct? You said we are not going to try to put together a Brady Bunch happy family right away - yet 12 hours later you are all out on the boat together? That was not your plan even a few days ago? What changed here so fast?
As to what went on after pushing forward with back to back outings right after the first meet, I tend to agree with you based on what you have written. It sounds like he gets away with a lot and is used to it. Sadly it's not going to end well if you try to change it - even if it's the right thing to do. See THIS is why you should have gone a bit slower. He may also not be happy about having to share his mom two days in a row - he's a little boy - they do that.
