I know the mantra well, plate, fwb, ons only. I realise you stay away from anything long term. Is there an exception though?

I've been fucking one for a few months now. 10yo daughter. Left the ex shortly after the birth because he was apparently too needy is her story. She has since went back to school and got herself a degree and job in a STEM subject, which in itself is rare for a woman never mind a single mother. Excellent cook, cleans etc to a high standard, child seems well adjusted in most senses. Has kept herself very well, slim, well groomed etc, about a 7 or 8.

She's been pushing for commitment recently which I knew was coming, even though I made it clear from the off I wasn't interested in that.

Question is do I just blow it off and forget about her, or let it run for a while and see what happens? Gut feeling is to slowly ease off and let her go. I'm 33, she's the same age for reference. Have 2 other plates on the side but haven't discussed them with her, both with no children but nowhere near as grounded.
