Is it real

My heart is in a state of confusion. Can a person be capable of true change. My thoughts are yes. But I also know and have seen first hand the other side of this destructive pattern. Can a person really want to love and and save another from the pain in their heart. Yes. But is it real or a ploy to get back into my life to hurt me again. I know these things are unable to be answered... But I also believe in forgiveness. Can a person like him ever really change or am I always going to be wondering about the lies and when it will end.
