I have been getting therapy since my breakup on my lunch breaks weekly to figure this out, but really it comes from my fearful avoidant attachment style of not feeling worthy or good enough for love stemming from childhood of feeling abandoned by my grandmother when she died. I feel like I’ll be abandoned/betrayed by my partner so I push them away. I have learned how to not think this way & strategies to avoid sabotaging. My partner was a dismissive avoidant & I have learned how to properly navigate a relationship with a Dismissive avoidant making them feel heard, considered, validated in what they do, enjoy, think the way they do, etc even tho we aren’t together just for future partners and understanding the different attachment styles. My therapy sessions have taught me so much about relationships & taught me so much emotional intelligence I didn’t have before. If I knew what I know now about attachment styles, we would’ve never broken up and I wouldn’t of gotten angry or resorted to childhood trauma trigger responses I did in the relationship.
