sorry to hear what you are feeling,, my dp left me and 2 girls in June, I wanted to work to save it but he didnt feel it was worth saving, it has been horrible for us all, extreamley painful but you will get through it and slowly day be day i feel better, (still find sundays awful though) You have to find some strength from somewhere, and concentrate on what you want, and make time for yourself,
I think he has been pretty bad to say this to you and then just to go off, rather than stay to talk it through, you must be feeling very confused, and abandoned, i really feel for you,
Keep posting on here it definetely helped me,
all the best xx
