Earl Thomas' wife is clearly done trying to make things work with the NFL star after the two were involved in that wild April incident ... TMZ Sports has learned she just filed for divorce.
According to court records, Nina Thomas put in the paperwork on Nov. 3 ... citing adultery as the grounds for ending the marriage.
Nina added in the docs that the couple has such a strained relationship ... there's zero "reasonable expectation of reconciliation."
It's interesting ... because Earl has seemed to put in a ton of effort to make things work since Nina was arrested for allegedly pointing a loaded gun at him back on April 13.
