Hi Shakira
Welcome!
Just wanted to chime in and give a quick tip about the takeaways. I've pretty much gone off them altogether, mainly because I know I can cook the same type of stuff that tastes better and is much healthier (I've also started to really enjoy cooking as a result!).
One thing that has really helped me out is to prepare in advance. Use the power of your freezer!!
I literally spend an hour every other Sunday afternoon and bulk cook a couple of meals, then stick them in the freezer. Then, on the nights where I just really can't be bothered to cook, or other things just seem to get in the way, I can just nip to the freezer, stick one of the prepared meals in the microwave for a few minutes. Then voila, a healthy filling meal for the evening.
I've actually found it less effort on those evenings than having to order a takeaway.
In terms of sticking to a preparation schedule it can help if you can make it a little bit of a social activity. So I prepare meals with my wife now and we hold each other to account to make sure we do it. So for you, if you can get your boyfriend on board then make a bit of a event out of it.
