Unfortunately I am very ignorant when it comes to lightning.  If I leave funds in the wallet for a long time and don't use them... do they expire?  If I don't enter the wallet for a long time, will I find them again?  I hope I have explained myself. THS 

 They don't expire, but the channel might eventually be closed and your funds will move from Lightning to normal on chain Bitcoin.

 and if they are moved to the normal Bitcoin chain, will I be able to see them and use them then?  if yes, how? 

 Yes. You can use them in the app or in another wallet.  

 A thousand thanks!  very nice.
