The only advice I can give is to get those trigger foods out of the house, and don't buy any more. If dh wants them, ask him to have them somewhere else and not bring them home. Looking at calorie counts was what kept me from buying stuff like that in the beginning. Now, I don't miss it, but at first you need some way of stopping yourself from buying more.
Also, come up with a plan for night time. I have a snack I save for the late night or middle of the night munchies: Yoplait 100 cal fat free yogurts. Some taste better than others, but the basics are all good: blueberry, strawberry, peach. That's my new "ice cream", so I save it for when I know I'm going to be weak and munchy. Since it's already planned into my daily food, too, I'm still on plan if I get up at 3 am and have a yogurt! You need something like that, plan for it, save it, then you can have it and not feel bad about it. A good dose of protein at every meal helps me, too...fills me up and keeps me full for a long time, so I'm not even hungry when it's time to eat again (I eat 5 times a day plus my yogurt snack some nights).
Anyway, I'm going on too long, sorry.

You'll find plenty of support here. Just cruise the forums, do some reading, and jump in any place you feel comfortable. You're doing great with exercise, it sounds like, so just focus on making small positive changes in your eating plan, and you'll get there. It took me a few months to really get to "clean" eating, but I just tried to do one or two things a little better than before, and when I got used to that, I did something else, and gradually I got used to a new way of eating. It doesn't have to happen all in one day.

If you don't give up, you cannot fail.
