To me, someone who is serious about their sobriety would be diving into that tonight, not hanging around a girlfriend who they just hurt very badly at a bar.
Not being snarky here but you need to remove the words.......not hanging around a girlfriend who they just hurt very badly.....from the above quote because really what it all comes down to is him and a bar.
And why does the girlfriend who he hurt very badly want to make it all smooth and nice for HIM? Your nice night out that you were looking forward to is now all clouded over with him and his issues not the kind of sorry or remorse on his part for hurting you badly.
