Is it possible to rebuild trust with your significant other after a betrayal?

when someone u trusted completely betrays u and doesn't try to mend things or let u know he knows what he did hurt u, it can't ever be right. u can't let him destroy who u were and still are. when someone does this to u its time to take back your power and get rid of him. if someone tells u they don;t love u anymore that's enough right there to end it and move on. problems can be resolved but he doesn't seem willing to communicate.
