Some people are poor communicators, whether that is written or verbal. It's hard to overcome a communication problem, and I feel for anyone who struggles with it.
Don't presume a lack of talking is an indication they're not interested. It could be, but it could just be a sign that they are shy and find talking difficult. You'll have to make most of the groundwork if you think it could be worthwhile - however be ready should it be the case they're just not into you.0
