LYING BOYFRIEND HELP PLEASE

HELP girls. So basically I’m with this guy, and I’ve been with him for about 6 months.. he lied to me one time about where he was.. I found out. He promised me he’d never lie again. A week ago he lied and promised me that he didn’t watch porn.. I found out. He promised me he’d never lie again. I hate lying.. today he lied to me again. I asked him what was in this secret box & he said money.. his sister showed me that it was full of lighters.. so he lied. What do I do?! Help please girls. I’ve explained to him how much it hurts and how much I HATE lying..
