if they still have feelings for you, then they can miss you; otherwise, they won't because you can't make or force someone to miss you
By showing her how much she needed you.
You cannot make an ex miss you if they don't feel it. Perhaps your ex does miss you. If they are not dating anyone else take the chance and contact them and meet face to face and discuss the relationship you had and ask them if they would like to try in the relationship again.
Your ex-boyfriend may miss you, but you have to keep moving. Keep in mind there is always a reason why they are an ex.
tu me manque ex
We cannot make anyone do anything. The only thing we can do is -- perhaps -- make them sorry if they don't do it. Since your ex obviously isn't sorry she's your ex, it is highly unlikely that you can do anything about the situation. Get on with your life. That part of it is clearly over.
As an Ex who ended it, yes, he will miss you. Every day. Every hour. Every minute. But, having felt he had a good enough reason to end it, all the missing in the world may not be enough to make him come back. Move on when you can.
usually, because you miss the person's companionship, and you still love them
No, it is not always true that guys don't miss their ex girlfriends. A percentage of guys actually do miss their girlfriends. It's not easy for some guys to get over their ex girlfriends anymore than an ex girlfriend trying to get over her ex boyfriend.
if you miss them you must still love them and ther for want to be with them
No one here knows you or your ex boyfriend. You can ask him if you wish to know.
Tell him you miss him and tell the truth
you know if your ex still thinks about when she\he calls you, text you, says stuff like: i miss you wanna come ver\ can i come over
