Where should I go?

I am Greek, married to a Korean woman, and lived together in South Korea with our two children (now 16 years old) in a rented apartment. I was responsible for the rent while my wife earned a modest monthly salary. She had an affair, and during the marriage I felt deeply neglected—once breaking my arm and going to the hospital alone, with no one from my family visiting or supporting me. That emotional pain hurt more than the physical injury. Eventually, I left Korea without notice, returned to my home island of Mykonos in Greece, and stopped all financial support for my wife and children. My assets and bank accounts are in Greece, some reportedly held under a trust. My wife refuses to sign divorce papers, and courts have indicated something about a three‑year period, though it’s unclear whether that refers to a separation requirement or a statute of limitations. I have no relatives, no friends, no parents—no one in my life except the family I left. I have considered returning to Korea simply because I am unbearably lonely, but I am also trying to keep busy with activities like hiking. I question who I can share my feelings with, and I have come to realize that going back might not be the answer. I remain isolated in Mykonos, relying only on myself, unsure of the future but still searching for connection and peace.
