STALKER EX!!

so my ex and I broke up 5 years ago he was very controlling and abusive!!! I ended up moving 5 hrs away and ended up. It didn’t go so well I was scared to go back home and see my dad in my own home town Coz of this guy and wouldn’t not walk down the street or go anywhere alone!! I had my dad my nan my mum my Aunty and my step dad and HIS OWN PARENTS telling him to leave me alone to the point cops almost got called!! I was scared out of my mind!! After that he would always be telling me what people are saying about me and what they want to do to me for “hurting him”.this went on for 4 years

5 year later he contacts me telling me his gf is pregnant and he wants me to be apart of his life and his gf wants to me meet me!!

I’m currently in a happy loving relationship and have a son/step... he has just found out about this and has been trying to be done friends with my partner again ( we were all friends in primary and high school)

My partner being so kind agreed to go see him today!! And told me after agreeing WELL didn’t I flip my shit...my ex has become friends with everyone I’ve dated and everyone I have become friends with when I moved he has!! He knows everything that have done it will do!! He always texts me making sure he is still doing “better” then me in life and if I’m doing better in his eyes..he will put me down for it. I’ve never had the guts to stand up to him before now!! As long as I’m with my partner I know I’m safe!! Well now I don’t feel so safe! Everyone I know that talks to him I will push out of my life coz I’m done with it! I finally had the guts to tell my ex to leave me alone and that we aren’t friends and left it as that but that was simply because of my partner coz I know I’m safe with him!!

Was it wrong of me getting so upset with my partner even tho he was just trying to be nice? I mean he knows everything my ex did to me like hold a knife to my throat ?! And he still wanted to go and see him? Like why??

Please ladies tell me I’m not in the wrong here
