hi roisin-
that's a lot of change in a short time. you don't have to make any decisions today.
for today, he is out of your space. he says he will go to AA.
for today, you have the space to yourself and he is off of the lease.
that's enough for today! take it easy, be gentle with yourself, treat yourself to something you enjoy...a nice big healthy salad? a long soak in the tub with some essential oils?
you don't need to make any decisions. let it all settle a bit and just take it one day at a time.
