This is easy. Been there and done that. This person was in a relationship with a person he/she loved dearly. The other person was basically playing with them. But no matter how much he/she got played they still felt so strongly for the person. Everytime he/she tried to act strong and stand tall like they were over the person, the person saw right through them and with the power they have over him/her they made them fall again. Really sad! Cause no matter what he/she does this person is keeping them down. They won't let them go to find love that is like the love he/she has for them!
