Man, that is fantastic! You can do it, keep it up!
I will say that (for me) there seems to be a "switch" that flips. Sometimes I'm just not interested in eating much. Then I'm ravenous. If and when you feel compelled to nonstop eat, remember your lessons and eat well, not junk. Fill up on better stuff.
The "switch" in you is now very confused. It doesn't know if you've started eating less because of famine, or some other issue. Humans have evolved in various ways but we are still creatures designed to survive and thrive. You may feel a compulsion to start eating heavily, almost unconsciously. That's normal. Although you may not feel hungry, do what you did and be sure to supply yourself with calories to function. If you short change yourself too much, you could:
1) faint (low blood sugar)
2) cause some weird body reaction (very unlikely)
3) get super hungry and eat all the goodies you can find! <--this is the biggest threat
Sustainability is the key - keep. it. up. Consistent effort. This isn't a "diet" but a life change for the better! It will take time to learn new and better habits. Every bit of exercise helps. Every little less food or better food helps.
My main method of easy exercise is taking the stairs instead of elevators or escalators, and parking further away than I can. I call it "living inefficiently." Everything in American society is geared to convenience and sloth (in both food and exercise). Be different.
It's hard when your spouse is not on board. But make sure you keep your eyes on the prize. Tell your wife you're just paying a penance for all of her delicious stuff, and soon enough you'll be eating more...but for now, you need to get some weight off.
Again, congrats. Onward to 10lbs lighter!
