Why do you allow him to confuse you?
Why don't you just tell him to leave you the **** alone?
Do you like the drama and so you let him keep himself forefront in your mind like he's been doing?
Get some female ballzzzz and tell him to stay away from you. He has a new girlfriend and the last thing you want to be is demoted to platonic friend or friend with benefits. Get the self-respect to do that and you'll feel the satifaction of your own personal empowerment.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
