Same here, I too feel she doesnt 'type' perfect english. English is fine just that some words are rather not used in conversational english. I have to go back to the chats to see what exact words or phrases they are. Although I mostly understand in what context she said those words.
btw, she sensed the age of ex poi on her own, that he was younger than me...that was one of the confirmation that she is connecting with me..
