As a result of the attack the woman suffered severe bruising, a collapsed lung and suspected broken ribs.
Messent also threatened to kill the woman if she said anything and refused to let her seek medical help despite being in severe pain.
Judge Cooper said the attack was a serious, violent episode and one Messent showed no remorse for.
He said Messent had numerous previous convictions, many of which were for violent offending.
"The victim's impact statement says as well as enduring physical injuries she has suffered from significant emotional and mental harm.
"It is clear you have a deep seeded streak of violence and have shown no remorse for your crime."
