Has anyone's marriage gone through postpartum depression..?

I'm almost 1yr pp and it really hit me after my LO was born.. Still today I'm trying to pull myself together. My relationship has suffered and I wonder how could we have gotten this way. I've been with my DH for 7yrs before baby and we were great, like more than happy. And after baby I feel like we've grown apart.. I know they say for better or for worse and we are definitely at the worse.. Any advice from other women who have gone through what I'm going through with your marriage.. Does it get better? Will I love him the same as before?
