Does it sound like they had by reading this?

Nothing about this implies . It sounds like the female is still hung up on her ex. The 16 year old probalby has a crush on her and wants a romantic connectoin, and the woman is just leading him on so she has someone to talk to about her ex (who is the one she really loves). They prbobly did cuddle and talk quite a bit, but it doesnt sound like went on , just based off of this
