That's co-dependancy. My husband and I do that. You simply begin to give over too much to the other person and end up feeling (or thinking you feel) their emotions and perhaps thoughts. I have worked hard on this. If my husband feels angry or annoyed, so be it. I don't provide any kind of solutions unless he specifically asks, I just let him wallow - it's his right to simply feel his feelings, isn't it. I don't have to own them, or solve them or anything at all. If it irks me that he's in a fowl mood - well that's my own right to feel fowl. It is really hard for my husband to deal with this. When he wants to control my mood he will stumble around with solutions and solving the situation so I just remind him there is nothing to solve and remove myself gently and kindly from the area fairly quickly.
