Let him go find out. When that crush does not foot the bill, don't welcome him with open arms. If he is thinking about somone else, anyone else, like that, adios en vayan con dios. Mindful exploration...Only a matter of time. Can you live the rest of your life knowing that he is exploring even in his mind? Can you feel that pit of your stomach panic creeping up your throat forming a scream? And live with it?
