Hi Lileth come on in, take a seat, tell us little bit about yourself.
If you put your height and weight and goal into MFP it tells you how many calories to have. It's a stingey bastard though so you can set your own calorie goal if you prefer.
If you really don't want to say anything to your DH just go for smaller amounts for now. When MFP tells you how many calories are in your mammoth perfectly reasonable sized portions you'll be too horrified to eat for the first few days anyway. Or was that just me? 
I'm RandallFloyd on MFP, I would recommend sharing your diary, it really is a great motivator. (Still living with the shame of my hula hoops and beer day)
Well done Lizzy, you're our very own Mr Motivator!
Very
of Double's gigantic house. I couldn't fit 5 wardrobes in my house never mind my lounge. I would recommend leaving for a week whilst someone else builds them though.
