Am I exaggerating?

Long story short, boyfriend said he didn't call me back because he was just lazy to stand up and leave the room he was in. He was in the same room his dad was sleeping in and he was lazy to stand up and call me back. I am FURIOUS. Would y'all be furios too? on top of that last night he was drinking and left my texts on seen with the dumb excuse he didn't have his phone on him. he "mistakenly grabbed his dad's phone instead of his" now he knows I'm mad and he's texting shit like "I want to marry you"
