trying to not be angry

I'm not even sure where to start this one. This happened just a little less than a month ago. I've been trying to simmer down first before I write about it just because I am so upset over it. Shaniqua has another child from a relationship after her and C. She had Lil' Shaniqua with Boyfriend #1. Her and Boyfriend #1 share custody of Lil' Shaniqua. She is currently living with Boyfriend #2.
C and I have talked many times about Bug and Sunshine having a little sister. Lil' Shaniqua's dad lives in our state. I called him awhile back and asked what his thoughts were on the kids trying to have a relationship with one another. He said we could def. give it a try because the kids are the innocent parties in all of this. But that we would have to wait because Lil' Shaniqua was going back to Shaniqua for the time being. We said that was fine. Just to give us a call when she got back up here and we would see if we could make this work for the sake of the children.
The day before Shaniqua gets Lil' Shaniqua she calls my phone and leaves a message about how happy she is that we all want the kids to have a relationship with each other. She's going to have Lil' Shaniqua and Bug and Sunshine should give them a call so they can start building their relationship over the phone. They are 7, 4, and 3. They don't want to talk on the phone! They want to play! Crackhead! Grrr.
But here is the part that really upsets me. She has Lil' Shaniqua call my phone and leave two messages for Bug and Sunshine. You can hear Shaniqua in the background telling her exactly what to say. I feel so sorry for Lil' Shaniqua because she is just another pawn to Shaniqua.
I have no problem with the kids getting to know eachother but Shaniqua is NOT dependable at all! She'd let them talk everyday for a couple weeks and then we wouldn't be able to reach her for another month. What are we supposed to tell the kids then?? GRRRRRR.
