not sure where this will go in It only makes sense to me

So kiddo spent some time with this dad yesterday. We met at Popeyes where they ate lunch. It lasted about 10 minutes. He and I didn't really talk. They went and opened kiddos presents in his truck. Then kiddo asked if he could go to his mamaw and papaw's house (my ex's adoptive parents) I agreed b/c I know kiddo has been missing them. So he ended up getting to spend about 4 hours with his dad and such.
when the ex dropped him off, he asked if he could see him more. I said yes, thinking he was going to arrange another time. He simply said ok then turned around and left. ??? wt? I was able to hold my tongue with some of the things he said or insinuated. Ugh he drives me nuts.
my boss asked me if he looked good and I can honestly say, there was no attraction there. I felt nothing. Just tension b/c I'm always on guard around him b/c I never know the stupid crap that will fall out of his mouth.
I do not miss him. I use to miss him when i thought about our good times, but I don't miss him even if I think about that. i think i've finally realized that theres no hope for us. not that i have been holding onto a hope of getting with him, but i use to care what he thought of me...now I dont. he's the one losing out on life with an awesome kid. he's a moron for it. and that makes him unattractive to me. i'm rambling nonsense again. point is, kiddo saw his dad...we will see where the ex takes it from here.
