"Basketball Wives" star Kenya Bell is finding out ... a marriage just can't hold up when you attack your husband with a box cutter -- because the guy just filed for divorce.
Former NBA'er Charlie Bell filed the papers in Michigan Court -- claiming there was a breakdown in the marriage (no duh).
Kenya -- presumably separated from Charlie at the time -- was famously arrested in May 2011, after allegedly breaking into the couple's home and attacking Charlie with a box cutter in front of their children.
Kenya was charged with assault with a dangerous weapon and domestic violence -- but struck a plea deal in which she avoided jail time ... pleading guilty to misdemeanor domestic violence.
Call to Kenya were not returned.
