Boyfriend away out all night :(

hello,

how do yous deal with when your boyfriend goes out for a ”lads night” and you don’t hear from him all night except he sent a video too show me but I’m pretty pissed off he’s ignored all my messages and is basically away just doing his own thing ?? Like yeah he’s allowed a lads night but its like he thinks he’s “got me” and he can still do what he wants and I can’t I’m about 6-7 weeks pregnant , any adivce please ?? Thanks xx
