Is there still hope for us? Will it ever get better?

My husband and I have been married for three years, together for nine. When we first got together he adored me. He really really adored and cherished me. We have gone through a lot of hard times and lately (past 2 years) he has become really cold and aggitated. Is it worth it for me to stick with it, I love this man with my whole heart. We have talked about it and it gets better for a week or so but that adoration isn't there anymore. I don't want to sound selfish or stuck on myself, but I really enjoyed it when he was fascinated with me. Now.. he doesnt really seem to care. Is there hope for a change?
