Im remarried now and all this debt I have is from the previous marriage. Can I file myself with what i have from my past or do i have to include my

Your wife does not need to file with you.  Your debts, current and past will be included.  If your wife is liable on some of those bills, she will still owe the money even though you get discharged from your obligation to repay it.  Bankruptcy does not discharge debt. I discharges the debtor's personal obligation to repay the debt.  The discharge is personal to the bankruptcy debtor.
