Over reacting ?!?

My so and I have been married for a year and I asked him to not talk to his ex bc when he gets mad he says shit like "your worse then my ex..," and shit he's just mad he doesn't mean it. But he agreed that he would not talk to her and delete her number and on Facebook. Then today like 8months later I get a suggested friend and it's her the ex and not one but two face books ! I got suggested Friends bc the only mutual friend is my so.we went to a friends house and I texted him this 
You know how sometimes when you scroll through Facebook they suggest people you might know ? 
Guess who I might know bc I have one mutual friend ....?
KARINA!!!!!!!!!!!!!! 
Guess who the mutual friend is ?????? 
YOU!!!!! 
babe I asked you to delete her bc I don't like that your friends with her especially since every time you get mad at me you bring her up ....
I don't wanna fight babe I don't 
It just shocked me when she popped up as a suggested friend when two face books of hers pop up as a mutual friend ..... Cause you said you deleted her....
I thought you did....until she popped up 
I hate it when your mad at me and you bring her up I don't feel comfortable that your friends with her....please delete her you always bring her up when we fight.....
Well anyway now you know how I feel I thought you did before well I don't wanna fight I wanna have a good time ....love you babe 
And he said shut up and laughed and I was like Anne I'm serious and he was like I don't care I ain't gunna play your childish games it's not like Ima fuck her she's in Cali and I was like why did you add her ? What was the point? And he was like I don't care be in your feeling you said you wanted to have fun tonight but you lie cause you over reacting .....ladies am I over reacting ?
