Jenelle Evans -- Domestic Violence Charge Dropped ... Working Things Out

Jenelle Evans and her estranged baby daddy are trying to work things out between them ... and step one was him not pursuing a domestic violence case against her.

Evans got popped last month for allegedly attacking Nathan Griffith, but the case was dropped Thursday after Nathan told police he didn't want to press charges.

A rep for Evans tells TMZ the pair are now on speaking terms and are working on their relationship ... for the sake of their child.

We're told Evans wants to put the past behind her and focus on the kid and her nursing career.
