EX has contact with DS every Saturday for the whole day.
He has been ignoring me at pick up and drop off for a few months and today his DM was with him and there was another woman sitting in the car.
He knocked on the door, I handed DS over and his DM starts a conversation about how excited DS is to see my EX and his GF (first I have ever heard about it). I said that I didn't know that EX had a partner and his DM said 'it's not something you talk about with previous partners'.
I admit I said a little too sharply 'If he had any respect for me as a parent he wouldn't have introduced a random person into my DS' life without letting me know'.
(EX was getting DS into the car at this point so wasn't in the conversation) His DM said that his personal life isn't any of my business and walked away.
I am fuming I am shaking with anger that he has introduced someone to DS behind my back, I feel like he has completely disrespected me as a parent and has been very sneaky by not saying anything at pick up/drop off.
AIBU to feel this enraged?
FWIW I do not have any feelings for this man and it is purely anger to due DS being introduced to a woman I had no idea about.
His DM has never liked me so her comments were expected, the fact that EX had introduced someone to DS was not.
