"I don't have a choice."

When I got "home" last night (I put this in quotes because even though I have my own place, I'm driving to my N's house at night and staying with him), my N was intoxicated and told me to "get my shit and get in the truck." When I asked him where we were going, he said, "Just get your shit and get in the truck. Stop asking questions." So, what did I do? Got in the truck. (I realize I should have gotten in my car and gone home, but for some reason, I didn't). Once we got in the truck, he shared with me that we were going to a bar to meet some of his friends. He told me that one of them asked him if it was OK with me. He then informed me that he told his friend, "She doesn't have a choice. She's coming whether she likes it or not."

WHY do I keep putting up with this???? I feel like I am absolutely about to go insane.
