He has been very secretive. His moods are up and down. One minute he is happy and the next he is irritable and on edge. He hasn't been eating much. He use to always have a big meal when he got home from work now he barely eats. He seems to always be avoiding me. He wants to be alone in whatever room he is in. I don't know. I decided to stay here and keep an eye on him and I am not liking the signs that I am seeing. There is definitely something going on. It may have been this way for a while but I am noticing it more now that I know he has been and could very well still be using cocaine.
