Help I'm worried

[Hezza]

My female Levi gecko hasn't eaten for 2 weeks and looks really tired what's wrong with her. there is a male in the enclosure as well and he is fine eating and everything."

The male may be dominating her or she may be exhausted from excessive mating.
I suggest that you consider separating them for a spell to give her a rest. See if that helps. If she's unwell, she should be kept separate until she recovers anyway imo.
