@strawharries Sometimes it's easier for us to learn from our mistakes and get over them than others. I know it's not my place to say but she could be hurt too. It seems like both of you are getting hurt in this situation, but you are talking it harder than she is. Or maybe you are just showing more emotions then her. You have probably already tried talking to her countless times instead just try and actually know how much she's hurting you and how much pain she's causing you. Tell her that a mother should be there for her child in a situation like this not making fun of her and teasing her about it.
