Following your heart...

"I am attached."
"But you are having a hard time."
"We must stop seeing each other."
"Stop hurting everyone."

You cannot help falling in love with someone you must not. It is impossible to control your emotions when you truely fall in love. In that kind of situation, it is very hard on everyone who is involved and the whole thing is very painful for everybody. Since everybody is suffering, it is better to follow your heart and do what is right for you than to live in confusion.
