Am I being petty?

Okay y’all so if I’m in the wrong just tell me but don’t beat me down please 🤦🏻‍♀️ anyways, my boyfriend is the worst texter ever when it comes to me. It bugs me so much and I don’t expect him to text me all day long , like I get that we’re adults and we’re busy but sometimes he won’t even text me at all. We do live together and when I get home I’ll see he’s on his phone just hanging out watching Facebook videos and stuff. It just bothers me that he rarely replies to me. And when I ask him about it he says he’s been super busy. When I get upset that he says that he tells me Im acting childish and to stop being petty. Like I text him today “good morning baby I hope you have an amazing day and I can’t wait to see you later “ and he never replied to it. Am I being petty to be annoyed about this?
