Good for you Ouch - why should you delete your thread?
Masses of projection and generalisation going on here! I think many posters either haven't properly read your posts or just plain don't care what you've said because you're the girlfriend of a separated man and must therefore be evil or deluded or both 
One or two posters have definitely strayed into 'unhinged' territory.
Trying to address your original post, just because someone instigated the split doesn't mean they are the 'guilty' party. I know in your case from a later post that she left for someone else but that's still doesn't make her 'at fault'. Anyway, fault doesn't play a part in the financial settlement.
I don't think that 'if' she is after a 'punitive' financial settlement that is alone red flag - it doesn't necessarily mean he 'has done something to deserve it'. You need to look at the whole picture.
Btw - My DH happily paid his XW the agreed maintenance, she kept the house so the children would have a stable home. I was there when she tried to give him his share of the interest on a joint account she'd closed, he told her to keep it, she insisted he took it. Not everyone is out for everything they can get. This was almost 20 years ago. Step kids are adults now, he paid maintenance until they left full time education. She was the one who ended the marriage, I'm sure not without reason though.
