I think everybody suffers.
My parents divorced when I was around ten. They didn't tell my brother and I about it; my dad just moved out of the house. But I caught on quickly, and realized what had happened.
First it just felt different. To be honest, I don't remember how it was like when my dad still lived with us. Now it feels right with just me my brother and my mom.
I didn't blame myself though. My parents weren't vigorous arguers, but things between them had been going downhill, I realized. And I couldn't have done a thing about it.
Overall I think it in a way 'opened my eyes.' I don't think I knew what divorce meant before the incident. Now I'm more observant of myself, relationships, and a lot of things.
I lived with my mom. So I found that my relationship with my mom strengthened very greatly so I was very comfortable around her. As for my dad, it was usually an awkward state. Definitely very much less than I feel for my mom.
I think that is my greatest loss from my parent's divorcing; my loss of contact and relationship with my dad. I wish that I could be more comfortable around him, but sometimes I even hate him.
If you choose to divorce, make sure you or your spouse (which ever one is not going to live with the children) will have complete access to take the kids out and spend time with them.
I told you how I felt from a kid's perspective. ;) But it's different for each child. How mature they are, their personality, their readiness for change, and more. Judge how well you think your kids would take it by things like that.
Whoo, that was long.
I hope I helped, and good luck!
