You drank because of your ex and because of someone you met? Seriously, I think you drank because you wanted to, it's the nature of alcoholism. The problem is, my alcoholism wants me dead and I won't let that happen.
Get a plan together, figure out what you will say to these people, too. I don't know if I would want to hang out with those who constantly drink. Today I hang with people who don't constantly drink.
I wish you well on your sober journey
