What Should I Do?

So its this boy i used to “talk” to but we stopped because he gave me his phone and I found out he was talking to other girls. He also lied about little stuff and things i knew the answers to. I told him we can just be friends because as much as i thought i should leave him, i didn’t want to. But we see each other in the hallways and stuff and when we talk he always says “are you gonna give me another chance” and he texted me like “everybody deserve second chances” and that he wont lie again I told him that I feel like I cant trust him no more but now I’m thinking about if I should give him a second chance, because like idk usually i be like ‘if whoever mess up or treat me wrong im leaving’. But i just like him so much after all that still.

Should I give him another chance ?
