Save money and avoid emotional anguish, ruined dreams and lost friendships by getting a divorce.
Pro More personal disposable income
Now your money is no longer controlled in a 'joint' account by a harridan witch you will suddenly find you can afford that PS4 Pro you wanted but she said you're too old for and besides "we can't afford it" while buying her 500th issue of OK magazine.
Pro Re-connect with long lost friends
As your social circle is slowly eaten away during marriage until eventually you know no one other than her and maybe one or two of her friends you will find after a divorce a renaissance in social interactions. That is as long ads your old friend sdidn't make the same stupid mistake you did. In which case like a loyal partner wait for them to be released from prison (marriage).
