He's been dating the wrong girl
Err... People have done stranger things. If he really wants to get out of it, and he's either too threatened by his partner (or her family) to break up or he's too ashamed to do it (for the who-knows-how-manieth time already), then I don't see why not.<br />
Desperate times require desperate measures, aye?
Sound like it's more trouble than it's worth. He'd have to be dumb.
