Also he has now a lot of cash from the female cop and apparently, his mom needs money. And he has received a death threat in his phone. I don't know why he would like to stay there. Just because of the girls? Apparently he doesn't have any problem in getting girls, since can have some kind of sex with like three different women in just one day, and two or three more fall for him, and also he's going to see Mia again in a few weeks. It would make more sense for him to take the cash, and disappear.
Truth is, if you analyze the plot of this game a bit, it has no sense.
