Unless the emotion leads you to make a decision with lasting consequences. How many friends have you had marry total twits? An acquaintance was engaged to marry a man who worked for me. I told her he was an alcoholic, a compulsive liar, a deadbeat who didn't pay bills, and he'd screw any woman who would let him. She raged that all her friends said things like that and we were all wrong. They married. Eight years later they were divorcing and she was complaining about all the things she'd been warned about.
A friend of me emailed me about the "love of her life". He was wonderful and the only problem was she didn't have enough income to support him, his mother, his son, the son's girlfriend, and the four dogs.
"Doesn't he work?"
"Well, he had a job in a bar but his parole officer wouldn't let him work there so all he has is SSI."
"Parole? He's a convicted felon. SSI? What's his disability?"
"It's mental and as for his conviction, it was all a mistake."
That one ended when the "mistake" took her for $57,000 and then sued her for domestic dissolution. The SOB wanted maintenance, what they now call alimony.
One should never make decisions emotionally. When I get angry I walk away until I calm down and can think rationally. Fortunately, I rarely get angry.
