Who told you that you can move on without having overcome the previous one?
After all, if you loved your ex a lot, it won't be easy to forget him and find the next one unless you're so "fake" and acting out or you're very insensitive and immediately lock your feelings in your heart and mind.
To find the next one, you have to get over the previous one, my friend, because the next one doesn't have any desire to hear constant whining and complaining about the ex from here!
Don't forget that you wouldn't want to be a substitute in a relationship, nor would you want to tolerate the other person's crying and pain.
And it's natural, my dear, when you break up, to hurt, to cry, and to break out. What would be unnatural would be not to hurt - well, it depends on the relationship, etc. - but think about how breaking up means that it wasn't worth it or that your relationship has simply come full circle.
After all, time, my friend, is the best doctor, and for me, the best doctor is ourselves.
When you break up and before you move on, have a dialogue with yourself, see what you want, clarify your feelings within yourself and think for once about yourself and no one else.
And after you've gone through the stages of separation and after you've gotten over the deceased, then yes, you're ready to move on!
But when we say below, we mean below without any backsliding, without maintaining contact and friendships with your ex, without keeping his things and gifts, having him blocked from all social media!
Because to move on and forget your ex from here on out, it takes crying, guts, and strength to overcome certain situations - always depending on the case and each breakup.
So never be sad about something that's over, but be happy about what's about to magically come where you least expect it!
Smile, because you deserve it and because it suits you!!!
