She still gets access to my kids?

My fiancé’s sister disrespected me on top of that has been emotionally abusive towards my finace and I for years. She’s also very controlling and entitled i have been going to therapy and I have been diagnosed with ptsd, anxiety, and depression.

I have since removed her out of my life however, my fiancé still wants a relationship with her which is fine. She still wants access to our children. I don’t know if I feel comfortable with that. Mainly given all of the emotional abuse that im still recovering from. I know she loves our kids it’s just if she’s capable of doing that to me who’s to say she won’t do that to them.

I don’t believe she deserves access to them. I believe her actions more than her words. Emotionally I feel that we’re better off with loving her from a distance.

I respect my fiancés wishes of still wanting her to be apart of the kids life. So with that being said I’m going to hand my kids over to a disrespectful entitled person 🫠 it just feels wrong and hurtful. Like I’m rewarding a person I want nothing to do with access to a very important part of my life. But I don’t want to be anxiously attached to my children. I’d rather just people please my way through this I guess than to be the “bad guy”. I’ve been trying so hard to change my perspective on this but I can’t. Depression here we come!!!!
