Am I wrong for feeling this way?

So long story short I had a very toxic relationship years back and I was a victim of domestic abuse so my partner who I am with now got me out of that toxic relationship and my ex her other ex was friends with my current partner as well flash forward to now my ex is out of my life completely but her ex boyfriend who randomly pops up now and again is becoming more friendly and I never liked him from the get go I warned him about my ex he didn't listen cycle continued to now where he broke away from her completely so now he is back in the picture in my life am I wrong to feel annoyed and partly mad that he still talks to my partner I an not the kinda guy to be jealous or control who she talks to but apart of me has that hatred to him and non trust ( small note her ex and my partner slept together before me and her got together)
