Boyfriend lied

So as you all know it was 420 yesterday anyways I was talking to my boyfriend on the house phone cause he broke his phone he told me his friend wanted to go to a 420 party but he's not gunna go I said you promise ? He said I promise over are relationship baby I'm not going in gunna stay home and talk to you , I said okay 5 minutes into our conversation he said his aunts calling the house phone and he needs to give it to his mom I said okay call me after he said okay love u and hung up I waited till about 4 o'clock in the morning for his call there was none , I went to school the next day and a couple of people told me he was at the 420 party and there was bunch of girls by his truck , at this point I'm literally devistated he lied went behind my back and broke my trusts , he then called I asked if he went anywhere last night he lied then I explained to him how people saw him and he then confessed , I told him I'm done he lied and broke my trust I told me Come pick up his things he then started crying saying no I said yes I'm not doing this with you I'm done I was in class so I said I had to go and hung up . He didn't call back and I don't expect him to he hasn't picked his things up either . I don't know what to do we've been together for almost a year already he's my first love , nothing can explain how much I feel for this boy . He broke my heart I'm devistated , I have no idea what to do w myself , I don't know if I should take him back or jus move on ? My mom doesn't want me going back and she Keeps telling me things are gunna get better but at this pint I feel like nothing can make this better .
