Most Helpful Girl
When she was with you she didn't want to be with him, because if she really did she would've dumped you the minute he started talking to her. She really did like you, but things sadly didn't work out between you two and when you guys broke up here came the ex who was tracking every move and waiting for this moment to get a second chance. It happens all the time, sometimes we get back with our exes, but that doesn't mean she doesn't appreciate the moments she had with you! What was her half smile communicating to you? It must have been such an awkward moment... Answering your question, it was neither. Feelings can go and come back, don't think she always had feelings for him.
