My girl has started having mood swings around me. She can give me one word answers and I feel like I’m the one putting in all the effort. It’s like she doesn’t want to be there. Plus, every time I ask her what’s wrong she says, “nothing.” And it becomes silent for the rest our time together. Last night, we were about to have sex and she just had an uninterested look on her face. I took her home in the car, but it she was silent for the whole ride.
