Male PPD

Does anyone on here’s partner have PPD? I know it’s definitely a thing, and I believe it’s affecting my husband. He’s turned into a completely different person. I have struggled with depression and anxiety before and I see a lot of the same things in him. I’ve talked to him about it and he agrees he needs to see someone, but then never does. It’s becoming really frustrating and I just want him to do something about it instead of falling deeper in the hole of being stressed, cranky, and mean all the time. It’s really hurting our marriage and I just don’t know what to do.
