When to leave EBF baby with bottle?

Baby is 8 weeks and has been exclusively breastfed. In the evenings she is quite fussy, breastfeeding every 30min, will cry if being held by anyone but me. This last week we’ve also introduced a 2oz bottle of my expressed milk and last night she took it all without fuss from her father - but this could be a fluke. I’ve been asked out for dinner tonight and I definitely don’t feel confident in leaving her with a bottle yet and she will definitely cry a lot because of her general evening fussing about being held by anyone but me. So I’m having big mama guilt about considering going out. At what age have you mamas gone out and left your little one with a bottle? How did it go?
