Relationship issue

Hi there again! I believe me and my man are having issues with our relationship. I'm an introverted person i barely socialise but Im very friendly to people whoever i talk with. My man is ambivert and loves socialising he does have quite a handful of female friends some being my classmates. He used to like this girl who he knew from grade 3 but before moving on to me he propsed to her but she rejected him. Knowing that he used to like her i get jealous and possesive very easily whenever he talks with her. But today he went over to one of his male bestie house where a female friend of his named Aisha came from canada and ngl shes so pretty. A short info Ive a bad case of low self esteem as ive been thru loads of traumatic stuff ever since i was a toddler. When I told him shes so pretty way better than me he said "Aisha is Aisha, she was always like this" That hit me on the spot. His tone was like he was trynna compare me with her. I might be overthinking stuff but that hurt when his tone was like that. Another thing he has a bad habit of seenzoning me. I say something romantic possesive type shit to him which might sound cringe as im not used to flirty stuff. Ive told him many times on call not to seen zone me coz i feel like ive hurt him or made him upset but he always gives this excuse "i dont do it intentionally i see your text but i get too busy then i forget to reply to your text." Talk about using this same excuses million times. Today i confronted him again about seen zoning me and heres what he said(screenshot down below this post). He said "idk what to say and when ive nothing to say its not seenzoning i just forget to reply to you."

I decided to deactivate my social for 72 hrs so he can't text me there because i feel like i need some time for myself and a break from his manly shit. Kindly advice me what should i exactly do with him..
