Feeling Like an Option

I hate that I feel like an option at times. I know our schedules aren't the best since he's deployed and we're on a 10.5 HR time difference..but sometimes, just sometimes I don't want to feel like an option. I'm always there when he needs me. I'm always there when he texts me. We snap every time he wants to but I feel there is something else going on. I don't want to think there is but women have this intuition. I don't know what to think. I'm head over heels for this man and he knows it. He knows I would do anything for him. I did, for the first, ignore his texts and he asked me why I didn't respond when he woke up. I simply stated the messenger wasn't working. What do I do? I don't want to hurt his feelings by telling him exactly how I feel. I rather just deal with it on my own and then forget it happened. Am I wrong in taking this approach?
