Well you recognized your own pursuit behaviour, good job.

Dont feel down about it - move forward and let it be in the past.

You asked for advice, I am gonna be blunt:

1. Did she ask you anything related to your kid or mutual financials? Not really, so LEAVE her alone.!

Her response is thick with that exact underlying message...

2. If you feel like validating (which I wouldnt here), then something like “Oh, I understand How that must be very frustrating.. I am sure you will figure something out”.

Drop the rope.....
