OK so mi best friend who is a guy has been kind of ignoring me! I've been through a lot w/ him and have always been there for him! He has a girlfriend but je used tooo call me all the time! And they been together forever! But now he calls me once a week tops! I asked him if I did something wrong but he claims I didn't! I'm just not sure wats going on!

He's probably finding it unfair to communicate with you so much since he has a girlfriend.
Him having a girlfriend is definitely the issue. Talk to him tell him you still want to be friends and it's not a problem if he has a girlfriend. His girlfriend is probably jealous of how he interacts with you so much.

Yeah... I'm betting his girlfriend said something to him about talking to you so much so he agreed to just talk to you once a week or so so that your not forgotten but so that his girlfriend is more important that you. That's just what the girlfriend wants... and he'll listen to her if it gets him laid.

Friends grow apart everyday it is a sad but true. It may not be about his girlfriend or about anything it may just be a natural growing apart process one that a lot of us including myself have gone through...

Id say the short and skinny of it is people grow up and life moves in and people move apart, don't give up on him just try waiting a little you may not know he has something's going n right now and just can't fit it all in.
