[M22] How much talking is too much/less talking in ldrs

So Ive been dating this girl for 6 months now. We met on reddit itself 🤙. We both agree that ldr absolutely sucks and used to fight over the most pointless things which stemmed from communication gaps just coz of the inherent nature of texting. We have met a couple of time irl including a vacation some time back and absolutely each other’s company. For the past months ive been busy in my job and often she seems to get mad over me not talking enough to her. 90% of the times I think we talk enough and feels like my life is majorly just either work or talking to her. Its hard to not feel like this is chore. Does it get better? Im confused if I can make the ldr work in the long term. Any advice from people who’ve been through this would help..? we both 22 btw.
