Unsure about my marriage?

We moved to a new state, and since then, my husband has been less attentive. He used to buy me flowers or a card once in awhile. He still tells me he loves me, but does nto take the extra effort to show it. I suffer from depression and it has been worse lately. When I told him, he still has made no effort. I try and do special things for him. The more I think about it, the less we seem to have in common anymore. Our interests are different, and I do not like to argue. How should I approach this?
