Actions vs. words - why did he change the locks if he's wants you back so badly?
I'm thinking it was a way to force you to come to him but he didn't think about the landlord. I wonder if he's now told the landlord not to dare do that again?
Something I read elsewhere...
"develop a practice of self care. Exercise in the way that is best for you, get the sleep that you need, eat healthy, take time in solitude and quiet, journal if that is helpful to you; listen to short guided meditations, practice gentle hatha yoga to calm the nervous system and strengthen the body/mind, listen to your favorite music that is a source of beauty and peace, spend time with a few friends whom you trust and can count on. Maintain a practice of self care now and throughout your life. You deserve to heal and you will. Healing and evolving are lifelong processes."
