One of the best pieces of advice my therapist has ever given me is that you can love someone who isn’t good for you, but you can love them from afar.
I just found your blog and love it already! I thought I would contribute the best piece of writing advice I ever got. A prof of mine said to "kill your children" - writers think of their work as their kids. When you "kill your children" you take out all the description, all clever dialog gets removed, take away everything you like about your work -if the bones you are left with aren't solid and the plot doesn't stand without the flourish - it wasn't good writing.
