Wtf?!

I have 16 days until my due date and now my boyfriend is acting so weird. He’s been so rude and short with me all day. He keeps saying he’s just angry but won’t tell me why.. I’m just so stressed out we’re going to fight before baby is born and I don’t want us mad at each while welcoming our little bean into this world 😓😓 do all dads do this? I feel like he’s just scared and stressed
