Your W is mean because of the stage she's going through.
If it helps I will write some really mean things my H said to me so you can see she won't stay mean always:
1. He told me the last 3 yrs of our M were 'a waste of time'.
2. He told me to get an abortion of Alisha (that really hurt).
3. Called me a 'sad dysfunctional little woman'.
4. Told the court he wanted the baby because I can't carry her due to disability.
5. Shouted at me to 'get out my house, you bitch!''
These are of course just a few.
But it DOES pass and it took OW to make him realise that 'no one else does it like you' (his words) and 'you're so clever, she just doesn't have your knowledge.'
Even if you only stay platonic with W, there will eventually come a time when her anger passes and you can at least be friends.
