How fast does a girl lose interest?

About how long would it take do a girl to lose interest? Days? Weeks? Months? She just doesn't seem to be as interested as she was. I know for a fact she's been really busy like the past two weeks, but the last time she initiated convo was about a week ago. When I've messaged her the conversations have recently been short and something like "got to go practice I will talk to u tomorrow". She has had her flute graded exam and I'd imagine has been practicing loads. Although 10 days ago when she was coming back from Berlin I got this text at half 11: "Heyyaaa!!! I'm 40 minutes from home!!! xxxxx". She rarely sends kisses so that's like a sure sign of interest, but could this interest have been lost by now?
