Hi sarahhealing,
I am so glad that you brought up this topic. I've been thinking about forgiveness a lot lately, too. And I recently listened to a podcast that really helped me to reflect on what forgiveness means to me.
I find myself really hurt about not getting what I needed from her, and sometimes I just feel really lonely. But lately, I think that a lot of my anger is surfacing as well.
I can very much relate to your feelings. My relationship with my brother broke down during and after the death of my father a few years ago, and we are trying to rebuild it. It's been really difficult. I have been holding on to a lot of resentment and anger, and I suspect he has, too. It makes "giving as before" very tough.
I can also see how my current definition of forgiveness has a hidden agenda related to my mom changing her behavior.
I think this is huge. What a great insight. So many of us tend to (wrongly, in my opinion) conflate forgiveness with condoning or approving of behavior that is harmful or hurtful. Or thinking that by accepting it, we have to continue to subject ourselves to it.
Recently, after having spent some time with my brother (much of it tense), when he was leaving to go home (that makes it easier, of course!), something inside of me just decided to open up to him. I'm not sure why at that moment. I guess I was tired of holding on, and cramping my heart into a tight little ball, if that makes sense. I had still been feeling hurt and defensive around him, but at that moment, something lifted and the weight and physical tightness of keeping that story running let go. It felt sweet and much lighter. I was able to say goodbye with lots of real connection and emotion. I felt free not only to connect with him, but with myself and my heart just felt more open in general.
Is that similar to how you feel in therapy when you get to those moments?
Does anyone have any suggested readings or even stories of how they've been able to forgive a BP mom or family member?
As a matter of fact, I do.

The podcast I mentioned above is by
Tara Brach, PhD. She is a psychologist/therapist and Buddhist teacher. What really resonated with me in the podcast was how she described forgiveness being about us. She describes that it is how we release our hearts from the armor that is trying to protect us, but which actually keeps us from opening up to
ourselves and others.
In other words, forgiving our loved ones who have hurt us sets
us free, not them. Free to love ourselves and others. Free to open to ourselves, other people, and to life and all its experiences. It reminds me of how we try to suppress just "negative" emotions with all manner of distractions, numbing, etc., but then wonder why we can't feel any joy either. We can't selectively suppress.
In a similar way, I suspect that we can't completely "block" one person from our hearts and be as open and intimate with everyone else as we'd like to be. And especially, with ourselves, which I feel is the most important, and makes everything else possible.
Thanks for letting me share. I'd love to hear your and others' thoughts.
