It is not too soon to move on as long as you are doing it for the right reasons. And the reasons are not to fill the void, to stop feeling lonely or to forget.
My 14 years marriage has ended emotionally long time ago, but practically in March. As much as i would want to find a distraction in a form of a man, i know i am not ready for it at all. And i doubt i will ever be. But thats the mindset i have right now, and this needs healing. And healing for me will not come with another relationship, as i have to stand on my two feet confidently and be happy with myself.
If you think you are ready to put yourself out there, then of course nobody can tell you it’s too soon. Do what you think it’s good for you, you know yourself the best, right ? Good luck π
