Pat and I have been married for almost 35 years - together for almost 38 and he still makes me laugh. So for me, humor is a big component to a successful relationship.
He is also my friend and while love can come and go, friendship is lasting.
We work really well together. It took us a while to figure out that each was good in different areas and that we really complemented each other. Now, instead of me trying to force my way on him, we work within our strengths.
DON'T TRY TO CHANGE YOUR PARTNER! It won't work - it isn't your job - and odds are, you won't like what he changes into.
Lastly, don't sweat the small stuff and have fun!
