my boyfriend doesn't trust me

[nadialove]

Hi everyone,
my boyfriend doesn't trust me anymore. Me and my current boyfriend dated for one year about three years ago before breaking up over childish reasons as we were both young at the time. We got back together a few months ago and decided to get serious and even talked about marriage. We both agreed not to tell anyone about us getting back together until we worked through our previous issues. I was too excited and wanted to tell someone so i told his sister who was close to me, i know its wrong i admit that, but he somehow ended up finding out and now he's called off the wedding plans and says he cant trust me. I love him so much. What should i do?
