The expectant mother endured cruel remarks and a lack of acknowledgment during her own pregnancy. It is understandable that she feels hurt and hesitant to wholeheartedly celebrate friends who were so insensitive to her joy. Attending the baby shower would only reopen old wounds and force her to suppress her emotions once again.
The plaintiff is clearly holding onto resentment and seeking justification to avoid supporting her friends. While their past behavior was insensitive, the plaintiff's refusal to attend the baby shower smacks of pettiness and an inability to move past perceived slights. It seems she wants to punish them for their past actions instead of acting like a mature adult.
The friends' initial behavior was undeniably callous and hurtful, causing the plaintiff genuine pain during her pregnancy. However, the plaintiff is also exhibiting a degree of self-centeredness by prioritizing her past hurt over supporting her friends' current joy. While her feelings are valid, choosing not to attend the baby shower will likely escalate the conflict and further damage the friendship. It's a childish tit-for-tat.
