DP left his ex because she was violent and unstable.
We got together a few months later, they were still legally married although obviously not living together.
This was 2 years ago. He asked her for a divorce and she cited 'adultery' as the reason, meaning he has to pay for it.
He didn't leave her through adultery.
She doesn't work so could have got the divorce for free rather than making DP pay for the whole thing.
DP agreed as he just wants the divorce over and done with.
They have a child together and he already pays £100 more maintenance a month than he's required to.
He is struggling financially at the moment and feels like she's being vindictive.
