LGBT: What do you do when you feel like this?

im kinda in a sucky situation. im trying to get over my ex who broke my heart over a year ago and yet still keeps me on the hook knowing that i would go back to her in an instant. well yesterday after a long time, i decided to go out clubbing with my friends. unexpectedly i met someone who caught my eye. she captivated me upon first sight. we have many common friends and i found out she goes to the same college as me. the only problem is she's straight. im just tired of being alone. do you think i'll ever find someone who will replace my ex? its hard, being and all.
