dang:/ seems complicated... if it were me i would probably go with mike, simply because your feelings for him at least sound stronger. but you kinda have to make a choice, cuz you're right its not really fair for aaron.. i hope i helped a little. good luck!!! i hope it all goes well for you:)
deffff mike! it seems like you reaallyy like him. if you love two boys, always go with the second one, the one that came after. because if you really loved the first one, there wouldnt be a second. hope i helped:)
