No. My brother is a proud Marine Corps officer. The guy she cheated with is lucky he’s still breathing. He wants to kill the guy. He fantasizes about it. He’s in therapy to get ahold of that anger. If he’s ever in the same room with the guy, it will be trouble. If he had caught her red handed back when this first happened, there’s no doubt in my mind he would have killed the guy with his bare hands.
OK, so he can write a letter with the consumer warning. The cooler he keeps, the more likely he can keep the boys (and warn them about girls like that). As understandably angry as he is at the guy, it is probably she that is the main reason for the trysts, and the new guy is probably mostly a gullible sap he could try to feel sorry for. She sounds like a cougar on the hunt, she is bad news.
