my boyfriend and i are always having arguments about his lies.

he always tells me that he would change but i don't see any changes. and i don't know if he is telling me the truth when im asking something because for me once you lied, its not 100% that i would still believe in everything.

please help me.. and he also tell me that she don't like the girl that is our former classmate.. please do help me. i really dont know what to do to him.

there was a time that i think that i should break up with him but i don't because i really love him.. please help me..
