Me and my N are done but I feel that he is biding his time and will somehow try to get back in my life.....
not unless they run out of narcissistic supply... in which case, they may come back for more.. or if their current boyfriend/girlfriend proves to be too independent and you were more of a doormat...
sexual seduction
Not normally, but it usually depends on in which way you dump them
Narcissist can be sadistic, it feeds their ego and gives them a sense of power to devalue and discard.
They will come back time and again it seems - just to see if you are still thinking about them!
Frankly, why would you want him too - he is your ex for a reason and he has been sleeping with others - I would scrap that and move on!!!
Tell him you want him back and if he doesn't want you after that then find someone else.
Ignore him
well yeah. but it matters. how did you lose them?
Narcissists need to always be complimented; dramatize their lifestyle or indeavors;adored; admired, etc., and it's 'running out of supplies' for the narcissist when they want to come back to the partner they were with. This means the narcissist is not being supplied to boost his or her's ego and they know they can more than likely get the boost (like a drug addiction) from their former partner.
Instead of looking for signs how about you be the bigger person and actually ask.
je retourne vers mon ex petit ami.
Yes probably. He may have a new supply and when that fails he will come back. It's a game they like to play. He will hurt you by devaluing you and leaving. Then he will come back and you will be so happy. He has won. You will then try to do everything to please him so that he won't leave you again. But he will. It's all about control.
