Boyfriend shows up drunk at hospital

So my due date is in 8 days. I'll be 39 weeks tomorrow. I started having cramps and diahoerra early this morning. My boyfriend and mother decided I should go to hospital just in case. Okay!!! We arrive the nurses check my blood, urine and sees if i diluted any. My cramps stopped and the nurse mentioned that I'll be admitted for abdominal cramps and I'm only 1cm diluted. My boyfriends goes home with my mom to drop her off because his plans were to be here all night with me. He decides to pitch up drunk!!! worse part he keeps speaking rubbish with the nurses. I feel so embarrassed right now. He tells me the reason why he had a few beers is because he is nervous. Even after I asked him so nicely not drink anything because anything can happen. Am I overreacting?
