*Taps 'Give-A-Fuck-Ometer'* Hmmm....

...doesn't seem to be working.

A woman had her teeth kicked out by her violent ex-boyfriend because 'she changed her Facebook profile picture'.

Lois Ashton has shared pictures of her horrific injuries, after she was kicked so forcibly in the face, three of her front teeth were knocked out and her jaw broken.

The 29-year-old, who now has to wear a partial denture, was attacked by ex-boyfriend Andrew McNair after a night out with friends.

McNair, who was jailed for 36 months, savagely kicked, punched and slapped Lois, after he saw she had taken him off her profile picture on Facebook.

Shocking! How can someone just snap like this, without any warning?

...she has bravely shared her story in a bid to help others who have or are suffering from domestic abuse.

Good for you, girl! Tell us, were there any warning signs?

She said: "He was lovely at first and so nice to me. But as the months went by he changed.

"I remember the first time he slapped me across the face."

Ummm, wait. Does that imply there was a second time?

"We were having an argument and I was shouting at him and he just slapped me.

"Another time he kicked me in the head and gave me a black eye."

I can feel my sympathy draining away.

"I should have left him for good at that point, but he was on the phone every day and saying how sorry he was and crying, so I would end up going back."

Not once. Repeatedly.

You can fix teeth and bones. You can't fix stupid.
