frustating situation

[DarkNick]

I have one friend who acts really wierdly ... sometimes he is saying to me lies and then he accepts that he's lieing (he told me that he was smoking and after 2 months he told me that he wasn't) when i ask him why are you doing that he just says i was bored...He also sometimes doesn't speak to me cause he says that i am boring.One time he tried to sunk me in the sea but fortunately i resisted...But some other times he is so nice to me one day i was at the beace and out of the blue he appeard , he sat next to me and he told me to watch at the stars and he couldn't stop talking...One other time we were playing voley with some other friends and we were at the same team.Our team won and he took me on his shoulders and he run all the beach through with me on his shoulders.he doesn't speak to me a lot but some other times we can't stop talking.Sometimes also when i'm saying about some problems he never gives attention he thinks that we don't have nothing to discuss but truly we have.When i give him some advice we end up fighting.One other time i was with my girlfriend and he sent me an sms i told him that we were going to chat later cause i was with her and then he was telling me that she was and he was blaming her and he was asking how could i still date with her but still he seems that he trust me he has told me thinks that he hasn't said to many ppl.

What's wrong with him? Does he hate me? Does he jealous my realitionship? Is he confused ? or what? :what: :(

You can't really tell what's happening with him! It seems to me that maybe they're is smoething in his life that is causing him to act unstable, alter suddenly. The best thing is to have a chat with him because it seems as though the lying may be a form of attention seeking. Does he have someone to confide in - this may be a reason for this or if you're spending too much time with your girlfriend and not with him, he may be trying to get your attention back.
But if this is not the cause of it, you really have such a decision to make. Is he worth having around? I just say have a chat and don't start jumping to conclusions yet.

Well...I tried to chat with him about that but he was always changing topic like he didn't want to tell me...I've tried many times...
