Well the campaign is much more over the top, than in previous one. I haven't tried multi yet, but I've heard good things about it, except the CQC (counter moves are bullshit). I have all the DLC's, as EA released them for free some time ago.
Graphically it is stunning, although I did have a few graphical bugs here and there, but it's a normal thing with games, running on Frostbite. Shooting is very satisfying and the damage mechanic is incredible, particles as well. Missions that take place during a typhoon are simply amazing.
The story is paper-thin of course, but that's not important. It's fast, action-packed and fun and that's what matters.
Also, don't worry - I'm positive that you will find more time to enjoy your hobbies and without the need for a divorce.
