what would you do to non committing friends?

Your friend whom you've known for 3 months is persistent to meet. he is straight forward nice person. helped you move into another apartment. he calls you and you call him on an ocassional basis does not anymore. When you tell him to keep in touch like, in a friendly way so he knows fair is fair. he doesn't make the effort anymore even when for him helping you move and give him a gift he doesn't meet up. he says he will meet up if you come to his area and we both make a date for it. but it never happenes ( he said something that offended me) . what would you do?

Friend # 2. You have been friends for months online, there is a connection but he has raging horomones.although your personalities are similar, you'd like to keep him as a friend. he ws going to school at the time you got to know eachother, but now he has graduated and not working. You found something you both have in common, (working out) but with a few attempts saying we would meet up, he doesn't call to say he is not meeting me. later on making excuses. what would you do?

thanks in advance
