My mom thinks I am acting crazy because my sister is dating my ex

Stick to what you are doing, You are doing everything right and keeping your daughter safe, She should always be number one. The way your mother is acting is not your problem its hers, I would cease all contact until such time as your mother and sister come to their senses.

Sorry but loyalty first, never date a siblings ex, your mum is definitely wrong

Even if there weren’t children involved, the sister and the mother really don’t give a damn about their sister/daughter

Your mom is in the total wrong! If you don’t grab your daughter, run, & cut that family out than you don’t care or love your daughter enough. I think you already know the answers & the right thing to do

No you are not crazy
