After reading the FDS handbook I learned so much. I know my value now and put myself first. But I'm having problems dealing with my sister who constantly belittles me with my past. Not sure how to handle it.

It's been quite a while since the break up, around two years and I didn't tell anyone about what happened between my ex and I because I thought no one would believe me.

He treated me badly, did not give enough attention, ignored me, was emotionally abusive, possessive and jealous, once twisted my hand and threw something at me etc. Nobody but a few friends and my sister knows about this. So everybody thinks he's a regular nice guy.

Whenever we get enough into a fight my younger sister always brings up how I'm stupid and was treated like shit and stayed in the relationship.

Since I'm older I'm always trying to guide her so that she doesn't land up in the place as me. She's has been dating someone for the past year (her first bf). When we fight or argue, she tells me that I'm just jealous of her because I'm not getting attention from boys lol.

Honestly I'm really happy rn. I have my life together, I'm better than ever. I don't want to date anyone rn and I do not need validation from men. I'm really growing on my own and love being single.

How do I deal with this? She does it to try and hurt me and remind of my past. We live together and I can't move out or anything. When she says stuff like that I just ignore her. Later on, I talk to her if it's about anything else. My question is should I be ignoring her altogether even when she's not acting that way? That might seem like I'm still hurting or that my ex still has power over me if I completely ignore her.

What should I do? How do I handle this while keeping my dignity and self-respect?
