The way I see it, youve got four options.
1. You play it right and get Mel and your kid back.
2. You play it wrong and get Britt.
3. You play it way wrong and lose both girls and your kid.
4. You play it Shakespearean, play it way wrong, lose everyone, fall into a pit of homicidal despair, you off both Mel and Britt and head to South Carolina on a search for Rebecca's bitch ass. You find her, but first off her bf Garcia cause he's at her place. You find her on campus and take her out, making a quick getaway and escaping into exile. Sean Joseph grows up with the sole purpose of tracking you down and killing you. At the age of 18, he attends Cuse rival UConn to spite you. He goes big in their football matchup, going over the 200 yards receiving mark. After leading the basketball team to a dominating win of the Orange, you come out of the stands to congratulate him. He proceeds to shank you with the kife he hides on himself at all times. He wins both the Heisman (the first freshman to ever do so) and the NCAA Basketball Player of the Year (the first person to ever win both) your two dreams. After receiving both awards, he realizes that the awards and accolades mean nothing to him and kills himself after falling into a deep depression. The End.
My guess, you try to get Mel to come back to you but dont mention Britt. This creates yet another fiasco of this sort which leads to Mel again not being able to trust you. Because of that, and you once again choosing Mel over Britt despite being in a quasi-relationship with Britt, you lose her too. However, by the end of your senior year, you have a Heisman wedding and live happily ever after.
