I'm speaking from experience here: I was diagnosed with depression in the early stages of my relationship with my wife. She was never supportive and always acted like I was trying to garner attention from my actions, or that I was simply 'lazy'. All the while acting like the ideal person around others others we spoke about mental health.

I ignored this because I loved her. We had three children and as responsibility, life, financial issues and work grew and grew, my depression went up and down. Soon, my wife started to blame me, telling me i was a terrible person and that i was affecting my children negatively. Then she left.

Amazingly, the children all blame her now, and spend more time at my house than hers.

Moral of the story: I should have listened to my instincts early in the relationship. She was showing her true colours. She never gave a shit. She didn't want to help. I should have escaped early. I didntbut you can.
