My mom got verbal abuse behavior when I grew up. I truly believe she loves me but didn't have the right skill and awareness to handle the relationship. She interated the issue from her dad.
I read some books to heal myself and tried the best to improve the relationship. We developed honest and easy relationship in those 2 years. I treat her with pretty low expectation. As time goes by, I feel stronger and stronger love from her.
I can read her face and give a tight hug before she starts verbal abuse::)))
I trust your feeling and your story. But just let me know, as your healing process goes on, you will feel differently.
Best wishes and good luck!
