Opening up more to your boyfriend

Delicate
My boyfriend and I don't speak to each other as much such as talk on the phone or text. For me it just like I always tell myself he's busy so I dont want to bother him and nor do I want to be that annoying as girlfriend who constantly text there man. However I'm starting to see a trend do men in there 30's not like to talk or text? This happens to most men I talk too. I want to say it may have to do with something on my part because I'm extremely shy and can be super awkward. In addition to I hate talking on the phone and sometimes even texting.
