if?what?why?

have you ever been in a relationship and sometimes feel lonely?? that's how I'm feeling right now. It's really weird and so depressing that I don't even feel like writing anything. I wish that I could talk about it with hubby and that he opens up more to me, but he's been so distant lately. Most of the time, when he's dealing with someting, he keeps it away from me.  I'm trying  to understand why it's so hard for him to share it with me  and why it's so difficult for him to understand what I'm feeling. questions, questions, questions, that's all my head is filled with and I don't know if I'll ever get all or the right answers.
