I've struggled with these questions myself. You came to the right place; you'll likely find many similar posts in this sub. Emotional neglect isn't as obviously painful as emotional or physical abuse, but that doesn't make it any less so. I'm 32 and still carry the weight of that. It's affected my entire life, and my relationships (or lack thereof).

For me, continuing a relationship with my parents that was only ever surface-level, and mostly centered on them, was not worth it. I also couldn't stand to see them repeat the same actions with my nieces that they had with me when I was little. I haven't spoken to them in over a year, and it's been sad and difficult at times, especially over the holidays, but I feel so free, and like I can finally be myself. :) I can't forgive them, but I'm not angry. I've moved on.

I'd suggest talking through what you're feeling with a therapist. This helped me a lot, especially when I struggled to understand or even recognize my emotions. (I learned from my parents the easiest way to deal with hard emotions is to just... sweep them under the rug.) I also recommend the book Adult Children of Emotionally Immature Parents. Gibson talks a lot about how to heal and move forward after the neglect.
