I like a guy on my college course and for a while I feel he has liked me too. He wanted some help and I texted him with some help. He said 'You're a total star Claire, thank you :) x' I never replied to this as I didn't know if I should. This was a few days ago. I saw him today and it was difficult to communicate as our desks had been repositioned. He has been back on the dating sites since which he is entitled to do so. I feel like crying as though I have messed up. How can I turn this around? I'm quite a shy person.
