Im confused should I break up with my current boyfriend?

My boyfriend has broken up with me 3 times now and this is his last chance, i even told him.

Every time he drinks or gets high he always thinks and ends up breaking my heart and once hes sober he comes running back to me.

Anyhow im kinda worried cause my boyfriend said he needed to talk to me in person about us and our relationship.

I asked him if it was good or bad and he said it was a good thing but i only think he said that so i would stop thinking about it and asking him what it was about. He lies alot about his feeling and what he wants to say so I think hes lying and hes gonna break up with me. Should I be worried about what hes gonna do? Should I just end the relationship fully?

Anyhow on the phone he told me to forget what he said and how we will talk tomorrow and then hung the phone up on me and didn't call me or text me back

so im confused what should i do and should I be worried?
