^ what Fo says makes a lot of sense - spending some time with them, sharing in their happiness may give you extra information, insight and empathy with the path they have chosen. And to be there for your brother in time of a big decision from him will hopefully bring you even closer together too - as well as his fiance.
Best wishes to you and your family Mike O 😃
I actually made sense? LOL Didn’t know I had it in me.
