I think I hurt my husband for the last time, help!?

All I wanted to do was talk about some issues that were bothering me. But for some reason it always comes out wrong. Now my husband thinks that I don't want him and he always makes me unhappy. When all I wanted him to see was that I make changes to accommodate the things he likes and I want the same in return. We do like a lot of the same things, but we also have different interests. I told him I wanted more experiences in life that I wanted instead of always doing the things he prefers. He tells me he doesn't understand why I think there are problems when he thinks things are great until I have my "meltdowns". I don't know how this mis-communication happens, but now I feel like I've hurt his feelings to the point where he won't get over it this time. We are both in school full time with two kids, and we are exhausted by the end of the day. And when I finally get the courage to have serious talks with him, I have held all my feelings in for so long that it just doesn't come out right. He won't even say he loves me back now and has been sleeping on the couch. I have been giving him space, but I'm worried about him. He is usually good at getting his homework done and now he doesn't feel like eating or doing good in school anymore. I'm trying to let him calm down a little bit, but how long should I let him be like this. And what can I say or do to let him know I'm sorry for upsetting him? I just want things back the way they were instead of this.
