Dina Lohan has a message for her ex-husband Michael about some recent interviews, during which he's claimed their daughter Lindsay
is abusing prescription pills: Stop discussing Lindsay's private life and focus on yourself.
Dina lashed back Saturday, telling PEOPLE: "Michael Lohan needs to focus on being a parent, paying child support, of which he is six months behind, and making up for all the years he was an absentee dad. And stop going on national television talking about his children publicly."
On Saturday, Michael told the photo agency X17
, "I'm going to see the judge this week...If I can't get a conservatorship, then I'm going to take her to an undisclosed location and get her straight. But I know I'm gonna get charged [with] kidnapping."
And during a taping Thursday of The Maury Povich Show
, Michael looked into the camera and relayed the following message to Lindsay: "I’m gonna do anything and everything I have to save your life, whether mom likes it, the public likes it, or anyone."
In response to Dina's comment, Michael tells PEOPLE: "She says I'm not focusing on being a good parent, but is she focusing on being a good parent?"
In fact, Michael says he's gone public for the sake of Lindsay. "Look, I know that sometimes in the past I've said things I shouldnt have," he admits. "[But right now] I have to help my child."
To that end, Michael says he's planning to meet with a judge and seek conservatorship, but a source tells PEOPLE that Lindsay herself plans to turn to the courts and seek a restraining order against her father.
"Lindsay is actively getting a restraining order, her lawyer have already been contacted," says the source. "She's scared. This is really serious."
