I believe in the institution of marriage. Of course being a Mormon we believe in eternity rather than just till death do us part. If you really try hard if you make it work it's blissful. But I also know a marriage that isn't working can be painful.
I believe God is managing affairs and that He doesn't need any advice from me. With God in charge I believe everything will work out for the best in the end. So what is there to worry about.
