My (22F) boyfriend Kyle (24M) and his dad (46M) own a successful car dealership together. For two years, I worked weekends there for free to help them out. Then I discovered Kyle was sleeping with THREE of his "car models" while I balanced their books.

When I confronted him, he laughed and said: "What? You expected monogamy from a guy like me?" His father overheard and immediately fired all the models. That night, he showed up at my door with flowers and an apology: "I raised him better than this."

One thing led to another... Now we're happily dating. Kyle is threatening to sue his own father for "stealing his girl," while I'm driving the Mercedes his dad gifted me. AITA for upgrading to the better version of him?
