advice?

my boyfriend and i are having communication problems... these days we lack conversation over the phone and texting just isn't what it used to be and he sees it as a big problem and I do too. we don't have cars right now so it's hard to see each  other and that frustrates me and makese so sad and hurt. I'm limited to phone calls and texts and sucks. Any advice on how to talk to him to make it better between us? the communication thing is really bringing us down and causing a huge problem in our relationship.
