yeah i agree with you @vict-vames
if he feels that u mean nothing to him, then u back off and let him have his way.
in situations like this, most individuals tend to believe that with time, things will change but don't be surprised if u face the plight alone.
when it comes to relationships, i don't think one should feel superior over the other, so since he feels that u are better off without him, u can talk things out with him, but if no changes is forthcoming then you can let him be..!!!.
