Helppppp 😭

Guys I got really drunk last night and my fiancé says I called him by my exes name😭. I literally don’t even remember having sex all I remember is being on the phone (which he said I wasn’t). I love my fiancé soooo damn much and haven’t thought of my ex in years. How can I make this situation better? What should I say or do? 🥺🥺
