What do you think about me telling my mom to stop inviting herself to special occasions?
Seriously? Is her attending these kinds of events a problem?
My mom is a self-centered bitch who wants to be invited to everything just to brag about herself.
If you have a problem with your mom, you should talk to her about it instead of excluding her. Other people may enjoy your mom being at that event and may dislike you if you exclude her.
Honestly, she's justa bitch. I'm going to raise hell when I talk to her.
I understand that you're upset with how she just invites herself to things but that doesn't mean you should make a scene out of it. Pull her aside one day and let her know that she's overstepping her boundaries. If you just come at her angry and emotional, she'll likely just think you're overreacting and ignore it.
