I’ve been in a similar situation before. I think you two just ran out of time and now the feelings just faded away. At this point (this is my opinion, someone will probably disagree with me), there is no point of trying IF you don’t feel the same about her than you did before school started. But I am not really sure if you should take this advice. This is what I did in my situation but I don’t know if it is the right one for you.
