My parents separated when I was 7, after some fights. In the first year I used to spend a weekend with my father twice a month, then he gave up to meet me because he had too work and he wasn't able to stay alone with his new mate if he had to look after me.
My mom has been very good to grow me but I still have some lacks. Just after their separation my mother got depressed and home became messy. Luckily she discovered the problem and then she solved it. I got some depression and anxiety disorders too (and I keep on having some).
My parents got back together 7 years later, so I was 14. I didn't agree with them so much, my father tried to have a better relationship with me, but maybe it was too late.
