First of all...u be a man and give her a choice...tell her what it is from the beginning, that u have a girl but u want her...so that point forward she can't get mad at anyone but herself if she feels played
I feel that b part of me rocks with that but the other half don't wanna tell the side chick shyt about my girl, because if (when?) it ends badly that bytch most likely gon go thru hell or highwater to locate my main girl and fukk my whole world up. I want to keep these two planets as far apart as humanely possible.
