Congratulations on deciding to get healthier now - it's a tough time of year, but you can start in with the healthy habits and by the time things settle down after the holidays, you'll be in good shape to keep it rolling when so many others will be just starting with their resolutions.
There is no secret quick loss formula - be conscious of eating healthier and in smaller portions, be aware of what you're eating specifically, and move more and don't let the number on the scale get into your head! Use a tape measure now and then you'll see what progress you're making. Sounds like your boyfriend is going to be there to help you - let him know directly what will help you the MOST. And count on him for that.
Sometimes support is much better than advice. Good luck!!
