She may just be curious or she may not have been totally over him.
He either still likes you alot or he hates you with a burning passion
Tell him you want him back and if he doesn't want you after that then find someone else.
If he won't talk to you, you should leave him alone. He doesn't owe you anything. You can't make someone like you.
your ex may want to stay friends with you. might be wanting to repair the friendship that was once there.
Stalking order, no contact order, grow up and move on.
Talk to him , tell him that you miss him & you want to work things out . Maybe you were confused when you broke up with him & now you're certain you want to be with him , just let him know & if the feelings are mutual he won't mind making things better again .
That you love her and want to catch up with her.
It is unfortunate that you were cheated on and then he left you but it may be the best for everyone at this time if you parted ways as it seems he is not ready for a committed relationship.
Anything you want, but preferably train up the Latias.
Keep things casual and simple.
You can catch up by buying the series or going on youtube but you must have good sound if you want to be able to hear it on youtube.
Just be honest with him & tell him how you feel if you want to get back together.Ask him if he likes you tell him you want to get back together & be patient with him.Or you could just bang him.
