he only remember you when he has problem.

This is the most common thing happening in friendship.For me if it is someone close to me,i would just directly talk to him but if they are not so close i would just go away and thats it.

It depends on what he's asking for. If he is asking for financial help, then I could not deliver anything like that. But if he wants an ear to listen, then perhaps I could give it to him. But if this is an on-going-off-going thing where he just forgets me when he doesn't need anything, then I'd just do what I can but not do more than a mile for him. It doesn't mean though that I'd end the friendship. But I won't take it seriously either. It's just like how kids are, when we need something to our parents we become all so concern etc., but when we're in our toes then we'd forget even to kiss them. So life is like that, you just don't get yourself tangled with his problems and just try to be there (without offering something that would truly divert my routine). This type of friend isn't worth cherishing, but everyone deserves someone to listen to them even if they don't deserve it.
