PARTNER - ALCOHOL - GIRLS - broken promises

I took my partner back after many mess up’s whilst being intoxicated and out clubbing. He promised to stop drinking, going out and I decided I’d make it easier for him and I’ll stop too. This weekend is my BFF going away party and I let my partner know and told him I really wanted to go, now he cracked the shits and said for me to “tell them” to have the party on Friday so he can go out Saturday and if they don’t then “f#ck them” and I’m not going . Now his promise was to stop it all so I can learn to trust him & see that his true to his word (this time) now his doing this shit again. Am I wrong for wanting to drink and should I just say eff it and stay home, I hate him treating me like I’m the one who has done what the BS that he’s been doing. I just don’t know what to do or if I even want to stay with someone like this.
