He told the Filthy Fellas podcast: "It was her decision and one that I had to accept.
If it was up to me - and I think a lot of men are like this - I'd probably be prepared to be unhappy for the rest of my life if [it meant] I had my kids in it. If I have my kids, I'm quite happy to sacrifice. It's a man thing. Relationships are what they are - they have highs, they have lows and people cheat - some people do, some people don't, but you figure a lot of things out.
The reality is we both were in a position where we were like 'are we really happy?' From her side of things, she'd ran the course more than probably me. But I was much more happy to go 'I'll be unhappy if I can stay in this house with you and these kids'. It wasn't to be for her, so we went our separate ways and that is that."
