It sounds to me like you ignored your feelings, texting and falling in love with another man's woman before she had broken up with the other man; sounds like she wants it both ways and you want it your way, never mind the difficulties she might be having with not being physically close enough to you to sustain a true relationship. What is wrong with the unattached women at your school?
