You can choose if you still want to love him or not but don't you think its pretty pointless to keep such a relationship? How can you have a bf who doesn't love you? What makes it worse is that you are already certain that he doesn't love you anymore.

Its like having a hairdryer that wont blow your hair, a fan with blades that don't turn or a speaker that does not protrude any sound. Whats it the point?

Move on.
