Planning Merryn's party

Me: JJ, we should plan Merryn's birthday party so we can get invitations out. How about we have it at the water park? I called about the pavilion but it's not available. But we could have a picnic nearby.

JJ: I would rather have it at home.

Me: I just think it might be easier in the park because the entertainment is built in, there are table there, all we have to do is bring food and balloons. It's the weekend after school is out and things are so busy now...it stresses me out to think of cleaning up the house for a party. 

Two hours later, after kids are in bed...

Me: JJ, we started talking about the party...can we decide? Park or house?

JJ: silence

Me: JJ, I'm open to doing it at the house but will we be able to communicate and work together?

JJ: silence

Me: JJ? Do you just want me to decide?

JJ: No! We will just cancel the party!

Me: JJ, NO. This is not about you and me. Sometimes you seem to be seething with anger towards me, and I don't know why. This is about our little girl. So please, either express an opinion and let me know if we can work together, or just let me choose.

JJ: silence

Me: okay, I guess I will choose.

JJ: fine, do it here.
