>>7 You're a good guy, 7. You just need to realize that some people have a very casual approach to life, and some have a very set routine. This may be something that shows the two of you to not be compatible in the long run. My advice is to just try to let your fears settle.
I don't know how to go about doing it, really, but you somehow need to put yourself in her place or get outside of your insecurity. Once you feel more at ease, see if it's your insecurity that motivates you to be together more often, or your desire to be near her. If it's the latter, then let her know that and see if you two can't set up an extra date a week or something.
Also, it might be a good idea to ask her if she's feeling bored, or like the dates are routine, even if they Are quality time. That could be a part of her decision-making process. (Ie, is it more valuable to me to spend my time on X or on X, and so far your X dates have just been composed of being around each other, rather than Also being fun/worthwhile activities in that sense)
