lonely and confused

i am not sure how i'm suppose to feel. I always feel lonely and I have talked to my husband about it way too many times. I feel that NOTHING has changed. I have tried my best to not get angry with him. i just this second finished talking to him about it again. He left anyway. Is it normal for us to talk about the same thing over and over and nothing to get resolved. He is always doing something and never has time for me. Does anyone have any ideas on how i can deal with this? I would greately appreciate it.
