Baby will not take a bottle!!! Help!!!

When she was first born we waited the 3-4 weeks before introducing a bottle or pacifier but when we did she took it just fine. We never really pushed it because I’m a SAHM and didn’t see the need to waste frozen milk or pump, but now it’s becoming a huge issue! My husband and I would like some date nights or go Christmas shopping without the kids or attend adult Christmas parties and I can’t go unless she’s with us! We’ve tried 6 different bottles, me being in a separate room, even me leaving the house completely. My husbands totally frustrated because he feels like he can’t help me out and I’ll be honest, when we have company over I sometimes don’t feel like whipping a boob out to calm her down. Any tricks to try??? I should mention she’s 3.5 months old. So it’s been a long 3.5 months of baby attached to me 😔
