Thanks everyone. It's just when I've messaged to thank her before she's always replied, just with a your welcome or see you next time. Just wondered why it had suddenly stopped. I know I don't have to thank her but I feel I should, I'm hard work and I find it difficult to open up and sometimes I feel it's easier to send a message with a thank you rather than to say it. Do you think I should stop mailing then if it's weird?
