I forgot this bit:
can someone give me a positive outcome of a similar story?
We aren't at the same level of suicide attempts, but my DH struggled with anxiety following the birth of our youngest.
She is DC4 so it's not like DH didn't know what to expect. He's a very hands on dad too and our eldest was 10 when dc4 was born, so we'd had a decade of learning how to parent together.
We had had a MMC and then struggled to conceive (when all previous pregnancies were easily conceived). This set the tone, he questioned his manliness for the first time. Once pregnant, I refused to discuss or acknowledge the pregnancy for a long tone, fear of getting too attached and ten having another miscarriage. By 20ish weeks pregnant I started feeling less anxious, but his anxieties set in.
Baby was born and this (unfortunately) coincided with an expecially stressful time at work. Well long story short, I really did everything with DC4 because DH just didn't bond, was too anxious and stressed to focus on the baby. He went through the motions with our other 3 dc, which helped me, but left baby for me to care for.
He went on anti depressant medication first. This didn't suit so was swapped for anti anxiety medication. Dosage changed several times.
He had 3 months off work followed by 8 week phases return. During the time off he rested. He slept a lot and slowly he got better. With time he started doing more with dd. By the time she was 12 months old he was more bonded. As she started walking and talking from 18 months or so they got much, much closer. There was a time when it would be always me DC4 came too. Not any more. Now DC4 had just the same bond with her Daddy as she does with Mummy.
It will get better. But he really needs the pressure taking off him.
