My old bf is coming out tonight! Help!! :(?

So I dated this guy James for a while, it lasted 1 year. This new Guy I am dating is a teddy bear :) He is soooo funny. I feel safe around him. He is just a sweetheart. My new bf is 6'5 325 pounds, my old bf is 6'2 215 pounds. Here is something that I love about a big man! Well my old bf is coming out to the bar today and he is pissed that I am dating this Big guy. My new bf is a Bouncer at this bar ( he is still in college ) I am really afraid something might happen. He wants to come in and talk and I hate him now, he is really abusive, do I tell my current bf that he is coming in!! I dont want there to be a fight at all. My big bf is a gentle giant but really protective ( he has 4 younger sisters ) and I don't know what to do or say!
