Need advice for a WW who left

[dwh15]

So my W just sends a text. First one in 3 days. And guess what it's about? Her exact words:
"I hate to bother u with this. But is there anything new on money situation? I'm struggling"

I already told her before I wasn't giving her any more help w/o a support order. It's like she chose to forget that conversation. Probably things we're buddies again after I helped her last week. Not sure of best way to reply, but I know she won't just let it go.
