What do I do?

My husband took all of his belongings recently and he's living with his sister for the meanwhile we were together for 9 yrs and married for a year. I know I may sound foolish for waiting for him to return but 9 yrs isn't something you walk away from so easily no I did not cheat but he did break the trust by keeping a female coworker a secret he told me how he let her drive his car for fun and he kept a secret from me how she gave him her number. He recently packed his things while I was at work at the time and he left his copy of the house key on my vanity. I am a old school fool and I'm holding onto the fact he's the only one I been with for 9 yrs and unfortunately I cannot get those years back. I know I'm foolish for wanting to wait for him to return I know the trust is broken but things can be fixed right?
