How long would you give yourself time to heal

If you had just come out of a toxic relationship after being together for almost 8 years, how long would you give yourself to heal? Would you give your self a few months, years, or just go with the flow and take it day by day? Im in this situation right now and its been about a month since i moved out. I have good days and bad days, the bad days are when im feeling really lonely and it feels like my friends are too busy for me so i end up missing my toxic ex. Then i feel like im in a rut. Id never go back to him though, not in a million years. Id just like some feedback if anyone has been in a similar situation and how long did it take you to heal and move on?
