one word messages and being a petty bitch

So my boyfriend is one word texting me or will say "true lol" "yeah lol" and I'm on my period so I'm so emotional about it and last night he didn't call me "princess" so I cried and then I woke up and decided to be petty cause of last night and I said "gm" instead of "good morning" and he said "morning" and I feel like now it's a game and he told me he was eating dinner (3 hours ago, who tf eats dinner at 2 pm) and I'm in a group chat with him and he's Texting the chat but not me, how can I get back at him and piss him off a bit once he responds ? (I understand this may sound immature but in all honesty I'm looking for tips and not a lecture, thank you)
