Doesn't love me enough?

My bf and his friends are going on a camp trip including girls. He once kissed a girl before drunk and I forgave him because I love him so much. But now I asked if there was gonna be alcohol and he said yes and that he's planing to get drunk. Idk what to think anymore. I have done a lot for him, including the pain I have been thorough when I forgave him for kissing another girl. And now he's putting himself in that situation again? Please help me and tell me what should I do. He's also telling me to walk away if I am not happy with our relationship.
