And to add to Mr. Bond's ideas, I would suggest be ready for a DNA test if he wants one. If he's had addictions, he's probably might be expecting people he trusts to try coercing him into recovery and into making life changes. Don't take it personally, if you can.
Remember to look at doing 180s if you can...changes that you should've always made but didn't do. 'being the best you can be as a wife'. Even if the D does happen, you'll be more prepared for future relationships (and motherhood!)
Don't forget to take a breather, Jessica...from what I've seen from my wife, having a baby does wacky things to the hormones!
