Help please


So me and my first love broke up and it was bad 😞. He cheated on me, and it’s been two months and he keeps saying how much he lives and misses me and me being me aka stupid I keep listening to it. It’s been hard on me, i haven’t talked to any other guy I’m not even comfortable to be around other guys and girls which sucks because he cheated I didn’t why can’t I move on ?? And what should I do ?
