Years ago I dated a guy and when it began to get serious, he started doing little things like complimenting me on an outfit and telling me how much better I looked in it than, say, what I wore yesterday. He did this a few times and I kept wearing what I liked, so he asked me why I wasn't wearing the type of clothes I look best in. I pointed out that it was his opinion etc. He got upset and pouted, talked about how he was just trying to be helpful, like the time he said I'd look better with red hair.
Big, bright red flags popped up.
I dumped him right then and there.
Later, he called to tell me that he really loved me and if I didn't give us another try, he'd kill himself. I said, 'Don't tease me.'
I never heard from him again, but no, he didn't kill himself.
