Cohabitation in CA - statute of limitations?

What is the name of your state? CA

Lived together almost 7 years, 2 kids. Not together 3 years (he got restraining order due to domestic violence).
1. Am I entitled to anything at all? (I am a stay-at-home-Mom to special needs child)
2. Is it too late to claim my rights due to years passed since we lived together?
3. Could Family vacations this and last summer together count towards "recent cohabitation" (yes, I gave it a chance, we tried to make it up, it didn't work.)
Thanks

I don't know that you're entitled to anything beyond splitting your common assets and debts (i.e. the ones that were purchased/created jointly). The kids will be entitled to child support, but you're not married to the guy and CA doesn't recognize common-law marriage.
