Maybe you can have her text you every 2 hours then increase it to 3 while shes doing things. Or! For one activity of the day allow her to message you after the activity is done...or let her initiate the texting.

Working may help, too. (Or volunteering)

In my relationship I often tell my boyfriend what I'm planning to do for the day and he'll do the same. Then we'll try to communicate based on our availability during our daily activities.
