I'm 36, my 11 year old son's mom passed away from cancer last year, and 2 days later cancer was found in my fiancee. She passed away 3 months ago.

I now share custody of my son with his stepdad... There's not much "normal" about it, but it's the best thing I/we can do for him given the circumstances. Family is what you make it.

I would focus on enjoying life and doing what you feel is best with no regard for what seems normal.
