Don't get me wrong I'm with you, and Rappers certainly aren't the standard bearer of what dating is like nowadays but Celebrities in general due to status and clout get WAY much more action thrown there way, so it's interesting to hear their perspective and experiences with relationships and dating, and SOME Rappers are okay and understand Girls are gonna have rotations, and guys they talk too. The smart ones anyway don't cuff these types of Girls, but they keep them around, and are okay with them getting passed around.
Tee Grizzley is a...pretty well known Rapper, and he's talked about this exact thing, he has a Child now with a girl he likes, but he's said it in Interviews that as long as the Girls he would talk to prior "played their role", he was fine with them fucking around because he was doing the same thing, but since he was the meal ticket, he would cut them off for more serious relationships when the time called.
