Communicate with him about your feelings. If after hearing your concerns, he continues to neglect you then you will have your answer. He doesn't care enough to try and make you feel like you matter. If this is the case, you are better off without him.
You alone are responsible for your happiness. Only you can give that power to someone else. Only you can take it away. The first person you must love unconditionally is yourself. In the end, you can't trust anyone else to define your place in the world. You must make your own place.
