LBH w/ a WW trying to save my M (4)

[gs9]

Need advice
WW called to ask about the equity again. I told her I believe 50/50 would be adequate because she would no longer be responsible for the risk or liability. Also, whatever she buys would be her asset. She got quiet.....I said "ok, have a good night. Good bye" and hung up

She called back to ask about D4. I answered her question. She went quiet for 5-10 seconds. I said "ok, good bye" She said " I can wait..." I hung up.

Just received a text from her it says " I actually thought you might think I contributed a TON to your financial welfare and I might be a little better off providing for your daughter you MIGHT consider not being selfish"

She's manipulating again trying to get more money out of me. No doubt and she won't get more.

But my question- Is this a perfect time for a truth dart. Do I message her back and say "Selfish? The only one this D benefits is you. That's selfishness. You are the one choosing this"

Or do I just ignore it?
