hi Erica,
from what you write, it sure sounds like, regardless of all the turmoil this stirred up in you, you are well aware that the actual discussion has nothing to do with you per se, that your kid seems in a respectful relationship, and that the friend they are talking about is negotiating with their partner(s).
far cry from where you found yourself, which was cornered. pressured. blindsided. cheated out of what you had signed up for.
anyway. yeah, you say you are broken.
maybe so.
then you say you don’t care.
really?
maybe so.
but even if the not-caring is true, there is a good chance a lot of this inside you could be healed. you could opt to find people to help you with that.
so that you won’t need to keep suffering.
