Nothing ventured, nothing gained. If your mate has a problem with it, it's his problem, not yours. Life is too short not to take a chance on this. If you still aren't sure, think on this - how will you feel if, in a few weeks, she's going out with someone else? If you're OK with that, then you don't fancy her that much. If you're not OK with it, and can feel your heart breaking into tiny pieces at the mere thought, you know what you have to do. Time for you to do the manly thing.........................
