His father thinks you are good because he may never find a daughter-in-law like you again and is reluctant to let go. I feel sorry for you too.
After separation, if you don’t have children, don’t keep in touch. The relationship of four years will gradually fade away. It’s not as long as a lifetime. Readjust your mood and make plans for your next step. Good people, no matter what kind of family they meet, Everything will be fine, I wish you happiness~
