I need helppp on my ex and my relationship!!! Urgent!!!?

Talk to him. If you really talk with him you'll be able to find things out. He can't just keep ignoring your calls... Just call him and make sure everything's okay. If you really love him, then you should try to work things out with him. And if he kissed you and held your hand and put his arm around you then he's probably got feelings for you, too. Unless he's just a major pig. And if he is, then he's not worth your time, anyways.
