Texting what is too much what is too little?

Apparently I had been texting my girlfriend too much and I hadn't seen too much of a problem and I didn't get a hint that I was smothering her since the quarantine hit lost my job and I had not much to do so texting her was a good time killer and doing projects on the side but it led to the demise of the relationship apparently.
