Most Helpful Girl
Ok... well based on what you wrote, it doesn't sounds like you have any reason not to trust her. I am the same way with my phone, I never check it, am constantly missing calls and forget to charge it all the time. Now, if her behavior had suddenly changed and she just now start to ignore your calls and forget to text you, when before she was more attentive to her phone then I would say she is acting sketchy.
But all that aside, it doesn't sound like you're really that interested in making things work with her. And if your feelings for her aren't strong enough, then you should let it be and walk away.0
