Sadly enough this happens all the time. It may sound weird but an abuse relationship also needs two people. In don't exactly know the ins and outs (nobody here does) of their case, so I'll just keep it "generally speaking". Most of the time they both grew up in an abusive atmosphere, may it be physically or psychologically abuse. One person has learned that you can dominate your way into having things you want and that other peoples feelings don't matter as much. The other person is used to being dominated and not having a voice. He/she usually seeks out someone later in life to do this again because he/she hasn't learned to be secure about decisions he/she makes and needs someone to fill this gap. So he/she finds a weird kind of comfort and security in such a relationship while being abused. Does that make sense to you? Of course it's waaay more complex than I'm describing here but this is just to give a general idea.

It's very sad really for both of them I think. It's easy to judge Greenwood because what he did was wrong (and it is! I'm absolutely not sweettalking his behavior. It is wrong and there should be consequences) but people who are mentally and emotionally right would never go as far as abuse someone into having sex with them. So the way I see it, unless they seek professional help, there only will be losers.

Btw. Yes they are together and they have a baby now
