No Idea What To Do?!

So I just bought a pair of size 9 jeans and they are too tight!!! I feel like such a lard and on top of it I feel like a lazy failure!  I have no idea how I did this before and now I am struggling to get back into it. I worked out 3 days last week and not at all this week. I mean I still have the rest of the week and I plan on working out tomorrow. It is just way too easy to say I don’t want to do it today I would rather sit on the computer and play my sims game.  I have cut pop out for the most part and when I got home and tried on the jeans and realized that they were to tight I threw out a half full carton on ice cream.  My biggest problem is dinner. I am good all day until dinner and then I really don’t feel like cooking so we just order a pizza. I can eat half a pizza by myself! Which is what I did for dinner tonight, we did go shopping tonight and we picked up some chicken and beef so I will be able to make dinner for a while. But I don’t get home from work until 6:30pm sometimes 7pm and by then I don’t feel like cooking a meal. My husband is next to no help. He can eat what he wants and still lose weight. He lost 10 of the 15 that he gained back from the honeymoon.  We still have to take Molly for a walk tonight so I will get a little bit of a work out in tonight. But now I guess I have a goal, to fit into those jeans!
