They are right, better talk to him whats goin on and regarding what you feel, there's nothing wrong with that. if im on your situation, maybe ill be planning to go but before anything else ill tell him first regarding my decision in that case maybe your friend will be able to talk to you.

well i alwayed help my cousins with these issues so like i always say, "FOLLOW WHAT UR HEART TELLS YOU NOT WHAT YOUR MIND SAYS" i know it might not be enough imformation or an answer but it usally sinks into you, I THINK that maybe you should call him and ask him NICELY i need to talk to you right away... face to face.. and ask him what going on becuz if you were friends with him for 20 plus yrs that means he trust and knows you very well, im not sayin you should stay or you should leave im telling u to follow ur heart and not ur mind and tellin you to talk to him

Trust him enough? Don't doubt moving in, help and support him on what he is going through.m

stay for him..

If he is going through some personal issues, my best advice to you is to indirectly approach him about it. Sit him down when he comes back or simply give him a call. Ask him if he's okay, if he needs to talk to someone, because according to what you've written here; i've come to the conclusion that he's an intensive introvert and people like him may not put it out there or tell you directly that he needs to talk, but this could be happening simply because he wants you to make him feel wanted.

this is very good advice,tho it seems hard not knowing what to do but i will take your advice...thank you

dont lose ur dignity n move out before he asked u to move or somethin like that...best of luck

better ask your friend directly and be ready to be hurt...
