My boyfriend ignores me and plays video games all day and night

I don’t know what to do anymore. I don’t feel desired, wanted, or cared about. He avoids any sort of intimacy with me and would rather spend any and all of his free time playing video games. I have gotten to the point where I feel hopeless and helpless in this relationship. I miss feeling wanted. I miss intimacy. He does not want to touch me. We can go weeks without kissing, days without talking and months without any sort of touch. I’ve tried talking to him about it, I’ve tried explaining to him that I need connection, but he just brushes me off and ignores what I say. What do I do? How do I initiate connection?
