Great responses! I used to get so angry when I would see the whole case of beer was gone and he would go out every night. I guess I let that anger go when I realized his actions weren't a reflection of myself and I began to take control of what I could and let go of what i couldnt control, which was his actions. Being angry was only punishing myself for his actions, I realized there was no point. I do still feel a twinge of anger when he is being himself, but I get over it quickly when I realize I am in control and can get Off this ride any time.
Also pp mentioned yoga, I second this. It has really taught me to step out of a situation and analyze what is the best way to handle things.
