sick of my baby daddy

Anyone else just so sick of your baby daddy ? I've been with this guy for 3 years + and I'm just so tired of acting like his mom . He turns 18 in August but I'm so mature and he's immature . Am I wrong to be pissed off that he goes with his friends after work every night and stays out late while I'm dealing with awful pregnancy symptoms . It boils my blood like get ready to be a father dude stop messing around .
