Any other dads have a partner facing post natal depression/blues?

Many mummies go through the post natal blues and I m sure the daddies go through the challenges together with them. My wife had a tough pregnancy which she had trouble drinking or eating, she had to go to hospital for IV drip several times because she was so weak and body was rejecting everything. I cannot imagine going through all of it again with her, it’s a part of my memory which I just archive away and not want to think about. We had so many challenges besides just the tough pregnancy, we just moved to her hometown (a new place for me) and waiting for our home reno to be done while she was preggy. We were moving from place to place as our in laws house didn’t have space for us, staying from hotels to relatives house for months before eventually moved in a week before delivery. We are now blessed with a beautiful cute little girl but our relationship hasn’t been going well. There has been so much of mood swings, nit picking over the smallest of things and lots of breakdowns for both of us. There are times where I just break down and cry hysterically after she is mad at me for days and dont want to talk or resolve the issues (often which I m clueless about). Many a times I ask myself, I have done nothing wrong or bad, I put my family on top priority and I only go to work or spend time at home with my family, no vices and the only thing I spend on is on my wife or for family related use. So why is she treating me like I have made a grave mistake? I understand that it is tough on her so I never blamed her or got angry at her. On a regular day I dont usually get angry too which she finds me odd. I have the privilege of a flexible working schedule and usually go to office once a week so I m able to spend the most precious time watching my child grow up. I love my wife and child but there are times which I cannot take it anymore, but I snap out of it quickly and look at photos of happier moments so I stay sane. If there are any other daddies out there that are having a tough time and reading this, hang in there, you are not alone in this journey. I’ve been through this rollercoaster ride and I m currently on one of the lowest points as I write this. I hope that sharing my story would help myself or someone facing a similar situation.
