Uniting metaphysically is completely okay because we all know that there are definitely others of us out there. We can be found on a special place called "The Internet".
If they don't care enough about you to be upset about loosing you, then why waste the time fighting for them. Don't loose yourself or disrespect yourself by continuing fighting, all your doing is allowing them to win. Be strong enough, brave enough, and smart enough to walk away. Be sure to walk away with your head held high... you don't want your tiara to fall off, princess(;
"All that is gold does not glitter, not all those who wander are lost; The old that is strong does not wither, Deep roots are not reached by the frost. From the ashes a fire shall be woken, A light from the shadows shall spring; Renewed shall be black that was broken, The crown less again shall be king." - J.R.R. Tolkien
