I agree with what Christina says about deserving someone who can contribute equally to the relationship. But I also agree with waiting4. Rather than giving him small opportunities to prove that he wants to communicate, why not just set a date with him and then be completely honest about how you feel, what you need, and ask if he is willing to put in an effort and give it another chance? At least that way you won't spend any more time like the last 6 months have been: constantly wondering "what if".
