My good friend Jessie has a girl and I want to make her mine?

Jessie is a friend, and he's been a good friend to be honest. But lately something has changed, Jessie got himself a girl and I want to make her mine. I sit there and watch her and I see her stare at him with those eyes, and she's loving him with that body, I just know it! I play along with the charade because there doesn't seem to be a reason to change. I want to tell her that I love her but I feel that it's a moot point. I've been funny and cool with the lines, but to no avail. Where can I find a woman like that of my own, or how can I steal her from Jessie?
