This was years ago, when I was married to my now ex-husband. I was offered a part-time writing job. I was so excited, I wanted to celebrate with a couple of friends, and my then husband. I've since realized he is a narcissist (a real one, not the term that just gets tossed around when people think someone is simply because they are vain). No. We're talking gas-lighting, love-bombing, manipulating, the works. For no reason whatsoever, he pouted the entire time. Didn't wanna order anything. Just wanted to sit there, sipping on his water, like a sad pile of sh*t, trying to make me feel bad about what? I have no clue. I was confused and mortified as he sulked and sucked the joy out of my little moment of success; in front of my friends, no less. I kept thinking why the hell did he bother to come if he was going to act like this? And WHY is he acting like this? Of course, he refused to acknowledge it later, when I inquired about his attitude. Even with witnesses, he denied behaving like a d*ck.
No apology offered. Narcs never apologize. There is a good red flag to look out for. If someone never says they are sorry when they have justifiably wronged you, or they do a fake apology that sounds like one, "I'm sorry you reacted that way." RUN. Change your number, change your job, change your address.
Also, if you go out of your way to help them out of a jam and they fail to thank you, dodge their future phone calls too. Users aren't worth your time.
Sidebar, he was such a miserable a**hole when things ever went my way. Of course, he wasn't like this when we met. It was months after we married these less flattering, selfish traits emerged. They can be sneaky. Keep a keen eye out.
