PPD second baby?

Backstory me and my BF have a 6 month old. Since she was born I had/am having some bad postpartum depression issues, crying every few days etc. And while I don't want another anytime soon,, I'm afraid that my PPD issues is wearing off on him and has put my bf off from having another baby at all. I want to have one in a year or two maybe (regardless of PPD) but I'm afraid he now won't want another one at all now because how I am struggling with PPD. Did anyone else go through this? Did you end up having another? Should I bring this up to my partner?
