Overreacting 🤔

So me and my now ex were into it because he say I always bring up females but that’s because he was a cheater and still is and so he just texted me out the blue and said I’m tired of you bringing up females and you got a whole baby that look like a old man. Like he clearly was talking about my 2 year old son and then when I told him stay tf away from me he said I was being a b**** and that all he said was my baby looked like a old man baby . I don’t want nothing else to do with him or I don’t want him around am I overreacting?

UPDATE: ladies I left him and it feels so damn good. I’m enjoying my children and I feel so relieved . Thank you all
