This is indeed an overwhelming adjustment - from what you said it sounds like your husband and you "fit" originally with alcohol being a major component in the relationship. Removing alcohol is certainly going to affect that, but it will most certainly be for the better, long term. What "better" is of course is not for me to say. Sometimes what's best doesn't look like it at first.
As a rule, our emotions go pretty haywire in early sobriety. It's best not to worry about strong feelings this early on, and advisable not to make any major life decisions early on because of the way our emotions affect the decision-making process. You may feel differently next week or in a couple months. This isn't to say you need to feel ashamed about how you feel - it just is what it is and doesn't have to affect your sobriety. Just know that your brain is currently wired to cope with life via a drug, and that drug is no longer in your system. Things are going to be emotionally rocky at times, but that is absolutely normal.
Just take heart in that you are doing the right thing! It sounds like you have figured out some very good reasons to stay sober. Now you can move forward with a plan for sobriety because you know why you are doing it.
