Sorry that you were offended by my response.
I pointed out your writings that prompted my responses.
I feel quite comfortable “assuming” (based on your posts) that your daughter was aware of your feelings toward / about her ex-boyfriend.
P.S. I just reread your original post which started this thread; I encourage you to do so as well if you want to understand my “assumptions”.
OP wrote:
“…oldest DD broke up with her BF and I’m devastated.”
“…I know he’s devastated.”
“I’m trying to be there for DD but I’m devastated too.”
“It broke my heart.”
“Best to swallow my feelings of disappointment and not initiate contact with this boy.”
“I fear I will always miss him.”
There is a lot more of your writing that I could quote in support of my “assumptions”, but I think this makes the point.
Wonder what the ex-boyfriend’s mother “assumed”.
