I've been reading some very excellent suggestions regarding this subject, but
one of the things that I haven't heard anyone say is that you should spend
time with your wife on the things she likes to do. If you spend quality time
with her, she will be more willing to let you go and do your own thing while
she does hers.
I think it's wonderful that some of your wives go fishing with you. I know
that can be trying at times (by experience), but it is also very rewarding.
The most important thing in my opinion is to have a quality relationship
where there is a mutual respect for each other where you can share time with
each other and truly enjoy each others company. Remember why you married her.
For what it's worth.
