Does it have to be that way?

Is it necessary for me to act that way? I know that he help me a lot in the past and yet he have done unforgivable things to me. I have no idea at all. By hearing what she said, i have been thinking is it necessary for me to act that way? Some say it's necessary but some doubt it. What am i going to do? I'm very confused. Did i purposely want to make it that way or it's just God's intention to make it that way?
