Oh I am so glad things are coming together, you have both worked so hard, I know how hard it is especially when working as well.....it’s so tiring and draining too, there’s just not enough hours in the day.
I think you’ve both done so well getting to where you are, just aim to do what you can, clear the rental house and then hand those keys back......all of the other jobs can be done, easier said than done I know because I am sure you want as much done before Christmas, hasn’t your boyfriend got any holidays to take from work (he may have saved due to your cancelled holiday??) only thinking if he has you could get everything done easier if he hasn’t got to go to work as well.
Regardless everything will come together, and you will have a lovely Christmas in your new home.
