If a woman does not like cuddling, could it be a PTSD from abuses?

Sure

Maybe, but maybe she was brought up in a household that didn't do cuddles so they're not natural to her, but maybe ask her

It could as well be many other things unconnected to any traumatic condition.

It could be so many things.
She'd be best placed to answer this qn.

Possibly. She could just be cold.
