My long distance relationship is taking all my time

I haven't been in a serious relationship in a few years and recently started dating someone. She lives in a different city (about an hour or 1.5 hrs apart) and we've been spending about 3 days a week together. Basically, I feel like this is too much time, or at least more than I want right now, because when we're together we don't get anything done other than spending time with each other (I'm a student).

He texts instead of calls

I have been in a committed relationship with a man for a few years now. Things are more or less amazing, except for the odd little thing now and then. Right now I'm beating myself up a bit because when he goes away for work (a few times a year for a few weeks) he doesn't communicate very well. When he first gets there, he hardly writes or calls at all, then we have one or two good phone conversations and by the end he resorts to texting instead of actually calling me... we actually have an entire conversation before bed over text!
