You are right. She is like that because of her background. She didn't feel much love while growing up and now that she found a guy who she feels love her, she is not willing to let go because she felt no one else could love her like that. What she needs to know is, if she loves herself enough, she wouldn't need to rely on someone that doesn't love her deep. Her love for herself will even chase those who can't measure up away.
Thanks again brother. Really appreciate you.
