Split with my avoidant ex today, feel sh*t.. help

Been with my partner (35f) I’m (m38)for about 15 months. I loved her more than my previous relationship of almost 12 years.

She is the usual avoidant type, prefers her own space, doesn’t give me back a tenth of what I gave her in love, financial, emotional etc… you get gist.

After she disrespected me Sunday night (happened many times in the past) I built up the courage to say enough is enough, and we aren’t compatible as both have different needs. Again she blames her mental health and actual health for most of the reasons then blocks me.

How do you overcome a breakup from an avoidant that you love dearly? It was me that broke up and I feel so depressed because of this. I only told her it needs to end as a kind of smokescreen to hopefully see she’ll change her ways but instead but it’s backfired.

Feel physically depressed even though I know it was for the better and I know I can do better than her but she’s the only thing on my mind. I can’t even leave the house 😪
