Relationship over?

Ive been with my boyfriend almost a year. He is the only man i have ever trusted. The past 2 weeks ive been ginding out about secrets after secrets and lies upon lies. Yesterday I gave him the opportunity to come clean about everything and if he did he would have complete amnesty and i would never hold anything he confessed over his head. He said i found out about everything and there was nothing left to know. Well today i found out he lied about it. I think im done. Im broken hearted and walking away from the man i love but i dont know of there is any other option left.
